An ordered low-temperature phase of barium nitro­prusside trihydrate studied by neutron diffraction

Crystals of barium penta­cyano­nitro­syl­ferrate trihydrate (barium nitro­prusside trihydrate), Ba[Fe(CN)₅(NO)]·3H₂O, have been studied by neutron diffraction in order to ex­amine the structural behaviour of the compound in the 20–120 K temperature range and to determine the structure at 105 K.

A new lanthanum titanium oxy­sulfide, La₁₆Ti₅S_17+xO₁₇, with x = 0.75 (9)

The tetragonal structure of La₁₆Ti₅S_17+xO₁₇ [x = 0.75 (9)] is based on an [La₂S₂] rock-salt-type framework that delimits [001] square channels containing chains of corner-sharing Ti(O,S)₆ octahedra. These chains are connected through La(O,S)_n polyhedra.

A novel zirconium polyoxometalate compound: (NH₄)₉[Zr₂(μ-OH)(H₂O)₂(AsOH)₂(AsW₇O₂₈)(AsW₁₀O₃₆)]·26H₂O

The title structure comprises two seven-coordinate capped trigonal prismatic Zr^IV ions, linked through an OH⁻ group, which are ligated to an [AsW₁₀O₃₆]⁹⁻ anion and to an [AsW₇O₂₈]¹¹⁻ anion that is capped by two {AsOH}²⁺ groups.
