Co_0.50VOPO₄·2H₂O

The title cobalt vanadophosphate dihydrate contains flat layers of VO₅ and PO₄ polyhedra covalently linked by Co^II ions coordinated to vanadyl O atoms. This is believed to be the first example of a layered vanadophosphate bridged by a transition metal ion in this manner.

Reinvestigation of Sr₂[Cu(OH)₆]

Sr₂[Cu(OH)₆] crystallizes in the monoclinic system in the space group P2₁/n (No. 14). The crystal structure is built up from mutually isolated highly elongated Cu(OH)₆ octa­hedra and trigonal Sr(OH)₆ prisms, forming layers parallel to (110). The Cu(OH)₆ octa­hedra are connected into an infinite three-dimensional framework of hydrogen bonds.

Na₁₀(Na,Mn)₇Mn₄₃(PO₄)₃₆: a new synthetic fillowite-type phosphate

The title compound, Na₁₀(Na,Mn)₇Mn₄₃(PO₄)₃₆, has been synthesized hydro­thermally. Its crystal structure is similar to that of natural fillowite-type phosphates and can be described as a hexa­gonal packing of three types of rods parallel to the c axis, which show an alternation of Mn, Na and P sites and lattice vacancies.

[CrBr₂(NH₃)₄][CrBr₄(NH₃)₂], a new chromium(III) complex

The title compound, tetra­amminedibromidochromium(III) diamminetetra­bromidochromium(III), crystallizes in the space group P (Z = 1). The structure is composed of octa­hedral trans-[CrBr₂(NH₃)₄]⁺ cations and octa­hedral trans-[CrBr₄(NH₃)₂]⁻ anions adopting a distorted CsCl-type lattice.
