Solid Solution Formation between Vanadium(V) and Tungsten(V) Oxide Phosphate

The solid solutions (V1–xWx)OPO4 with β-VOPO4 structure type (0.0≤x≤0.01) and αII-VOPO4 structure type (0.04≤x≤0.26) were obtained from mixtures of VVOPO4 and WVOPO4 by conventional solid state reactions and by solution combustion synthesis. Single crystals of up to 3 mm edge length were obtained by chemical vapor transport (CVT) (800 700 °C, Cl2 as a transporting agent). Single crystal structure refinements of crystals at x=0.10 [a=6.0503(2) Å, c=4.3618(4) Å, R1=0.021, wR2=0.058, 21 parameters, 344 independent reflections] and x=0.26 [a=6.0979(2) Å, c=4.2995(1) Å, R1=0.030, wR2=0.081, 21 parameters, 346 independent reflections] confirm the αII-VOPO4 structure type (P4/n, Z=2) with mixed occupancy V/W for the metal site. Due to the specific redox behavior of W5+ and V5+, solid solutions (V1–xWx)OPO4 should be formulated as (VIVxVV1–2xWVIx)OPO4. The valence states of vanadium and tungsten are confirmed by XPS measurements. V4+ with d1 configuration was identified by EPR spectroscopy and magnetic measurements. Electronic spectra of the solid solutions show the IVCT(V4+ → V5+) and the LMCT(O2- → V5+). (V0.74W0.26)OPO4 powders exhibit semi-conducting behavior (Eg=0.7 eV).

Anti-polar 2D-metallicity with tuneable valence Wx+ (5 ≤ x ≤ 5.6) in the layered monophosphate tungsten bronzes [Ba(PO4)2]WmO3m–3

The newly discovered series of layered monophosphate tungsten bronzes (L-MPTB) [Ba(PO)2]WmO3m–3 consist of m-layer-thick slabs of WO6 octahedra separated by barium-phosphate spacers. They display a 2D metallic behavior confined in the central part of the perovskite slabs. Here, we report the missing m = 2 member of this series, containing the rather uncommon W5+ oxidation state. We have analyzed its structure-property relationships in relation to the other members of the L-MPTB family. In particular, we have determined its crystal structure by means of single-crystal X-ray and electron diffraction and investigated its physical properties from resistivity, Seebeck-coefficient and heat-capacity measurements combined with first-principles calculations. All the L-MPTB compounds show metallic behavior down to 1.8 K without any clear charge-density-wave (CDW) order. The m = 2 member, however, displays an increased influence of the spacer that translates into anisotropic negative thermal expansion, reversed thermopower and reversed crystal-field splitting of the tungsten t2g orbitals. Our analysis of the full [Ba(PO4)2]WmO3m–3 series reveals a systematic and significant W off-centering in their octahedral coordination. We identify the resulting anti-polar character of these W displacements as the crucial aspect behind the 2D metallicity of these systems: It leads to the presence of bound charges whose screening determines the distribution of mobile charges, tending to accumulate at the center of the [WmO3–m] block. We argue that this mechanism is analogous to enhanced conductivity observed for charged domain walls in ferroelectrics, thus providing a general design rule to promote 2D metallicity in layered systems.

Niobium-insertion into αII-VOPO4: Tuning catalytic properties for selective oxidation

A holistic understanding of the key catalytic features of vanadyl(IV) pyrophosphate enabling high maleic anhydride (MAN) yields in n-butane oxidation has fostered a debate which has continued since the finding of the catalyst. Under reaction conditions, vanadium(V) orthophosphate structure fragments were detected on the surface of the catalyst. However, single-phase αII- and β-VVOPO4 reveal a much lower catalytic performance. This study shows that introducing Nb into αII-VOPO4 forming a solid solution (V1-xNbx)OPO4 yields a bulk material with tunable catalytic properties. Selectivities of SMAN = 48% at a conversion of Xn‑butane = 30% on (V0.1Nb0.9)OPO4 are shown to be related to the isolation of surface V-sites, which surpass known VOPO4 catalysts by far. A boost in the overall n-butane consumption and MAN selectivity under alkane-rich feed conditions is shown to be another characteristic of (V1-xNbx)OPO4, leading to a highly increased MAN productivity. XPS studies reveal that a progressive replacement of V by Nb induces a reduction of the averaged oxidation state of near-surface V from +4.7 to +4.3, a finding that correlates linearly with an elevated MAN selectivity. This study experimentally confirms site isolation and electronic environment of the near-surface V-species as the key catalytic properties, from which catalyst design rules are derived to optimize partial oxidation reactions.

The first triel oxonitridoborates AlB4O6N, Al0.97Cr0.03B4O6N, and Al0.83Cr0.17B4O6N being in competition to ruby

AlB4O6N, Al0.97Cr0.03B4O6N, and Al0.83Cr0.17B4O6N are the first
representatives of the recently established structure-family of
oxonitridoborates containing Al3+. These compounds are isotypic to CrB4O6N
and are synthesized in a multi-anvil press under
high-pressure/high-temperature conditions of 7.0 GPa/1350 °C. Structural
refinement by single-crystal X-ray diffraction shows that they crystallize in the
space group P63mc (no. 186) with two formula units per cell. Detailed
characterization including high-temperature X-ray powder diffraction
(HT-XRD), electron probe microanalysis (EPMA), measurements of second
harmonic generation (SHG), hardness, photoluminescence properties,
vibrational spectroscopy, and band structure calculations reveal intriguing
physicochemical properties that strongly resemble the famous material ruby.

Lithium Copper(I) Orthophosphates Li3–xCuxPO4: Synthesis, Crystal Structures, and Electrochemical Properties

Along the quasi-binary section Li3PO4 - CuI3PO4 three different phases Li3–xCuIxPO4 each with extended homogeneity range occur under equilibrium conditions (650≤ϑ≤700 °C). According to single-crystal X-ray structure analyses Phase 1 (0<x≤0.7) adopts the HT- or β-Li3PO4 structure type [Li2.6CuI0.4PO4, Pnma (no. 62), Z=4, a=10.4612(2) Å, b=6.1690(3) Å, c=4.9854(2) Å, R1=0.023, wR2=0.062, Goof=1.12] and Phase 2 (0.9≤x≤1.8) is isotypic to LT- or α-Li3PO4 [Li2.05CuI0.95PO4, Pnm21 (no. 31), Z=2, a=6.2113(8) Å, b=5.2597(7) Å, c=4.9904(5) Å, R1=0.040, wR2=0.108, Goof=0.98]. A preliminary structure model for the copper-rich Phase 3 (2.1≤x≤2.8) ["Li0.6CuI2.4PO4", P3 (no. 147), a=6.223(1) Å, c=5.3629(5) Å] could be refined to R1=0.07. Sharp 31P-MAS-NMR resonances observed in the spectra of Li2.6CuI0.4PO4 (δiso=10.4 ppm), Li2.05CuI0.95PO4 (δiso=12.4 ppm), and Li0.84CuI2.16PO4 (δiso=10.9 ppm) provide evidence for the absence of paramagnetic Cu2+ ions. Pure copper(I) orthophosphate CuI3(PO4) exists as a homogeneous melt (≥800 °C) and can be obtained as thermodynamically metastable solid by quenching. It is isotypic to Phase 3 [a=6.284(3) Å, c=5.408(5) Å]. Electrochemical delithiation of Li2.05CuI0.95PO4 (C/10, C/30) indicates two partially reversible oxidation processes between 3.75 V and 4.80 V (vs. Li0/Li+).
