A new polytype of orthoboric acid, H₃BO₃-3T

The trigonal polytype of orthoboric acid consists of pseudo-hexagonal sheets of hydrogen-bonded B(OH)₃ mol­ecules, with van der Waals forces binding adjacent sheets and repetition after every third sheet.

A new aqua­hydroxido­copper(II) oxo­vanadium(IV) vanadate, Cu(H₂O)(OH)VO(VO₄)

Single crystals of a new aqua­hydroxido­copper(II) oxovanadium(IV) vanadate have been synthesized hydro­thermally at 473 K. The three-dimensional structure presents layers of vanadate tetrahedra and distorted oxovanadium octahedra connected by Cu atoms.

A synthetic zinc tellurium oxochloride, Zn₂(TeO₃)Cl₂

Zn₂(TeO₃)Cl₂ has a layered structure in which the Cl atoms and the 5s² lone pairs of the Te^IV atom protrude from the surfaces of each layer towards adjacent layers, which are only held together by dispersion forces. The compound is isostructural with the synthetic compound CuZn(TeO₃)Cl₂ and the mineral sophiite, Zn₂(SeO₃)Cl₂.

A mixed-valent niobium oxy­sulfide, La₂Nb₃S₂O₈

Dilanthanum triniobium di­sulfide octaoxide, La₂Nb₃S₂O₈, crystallizes in the orthorhombic space group Pnnm and is isostructural with the Ln₂Ta₃X₂O₈ (Ln = La, Ce, Pr and Nd, and X = S and Se) family of tantalum compounds.

KHCoP₂O₇·2H₂O: a novel acidic pyrophosphate

The title compound is a new acidic pyrophosphate metallate. It consists of cobalt–pyrophosphate layers joined by K⁺ ions and H-atom bridges. The Co²⁺ ions are octahedrally surrounded by four pyrophosphate O atoms and two water mol­ecules.
