Tri­ammonium Trimetaphosphimate Monohydrate

(NH₄)₃(PO₂NH)₃.H₂O contains trimetaphosphimate anions, ammonium cations and water molecules linked by N—H⋯O and O-H⋯O hydrogen bonds.

Refinement of the Superstructure of C-Type Chromium(III) Tris(metaphosphate), Cr(PO₃)₃

The superstructure of C-type Cr(PO₃)₃ has been refined from single-crystal data. The CrO₆ octahedra are only slightly distorted and the PO₄ tetrahedra show typical geometry for metaphosphate chains.

Tetra­carbonyl(tetra­phosphorus hexaoxide)iron

The Fe atom in [Fe(CO)₄(P₄O₆)] has trigonal-bipyramidal coordination geometry and the axial P₄O₆ unit shows distortions similar to those observed within the series P₄O₆X (X = O, S, Se).

A New Quaternary Borocarbide, GdRh₂B₂C

The structure of GdRh₂B₂C consists of tetrahedrally coordinated Rh₂B₂ layers and GdC NaCl-type layers which stack alternately along [001] via short B-C bonds.

Na₈H₁₈[{Er₃O(OH)₃(H₂O)₃}₂Al₂-(Nb₆O₁₉)₅].40.5H₂O

The structure of the [{Er₃O(OH)₃(H₂O)₃}₂Al₂(Nb₆O₁₉)₅]^26- anion is compared with that within the isomorphous Eu complex. The smaller ionic radius of Er³⁺ induces a contraction of the central [{Ln₃O(OH)₃(H₂O)₃}₂]⁸⁺ cluster with a resultant attraction of the five [Nb₆O₁₉]⁸⁻ groups towards the anion centre.

The First Beryllium Periodate: Be(H₄IO₆)₂.4H₂O

The crystal structure of Be(H₄IO₆)₂.4H₂O has been established by single-crystal X-ray methods. Two of the H atoms within the [H₄IO₆]⁻ anion are disordered over split positions.

K₂Be₂Si₃O₉, a Potassium Beryllium Silicate Framework Built from Edge-Sharing Be–O Tetrahedra and Three-Ring Silicate Tetrahedra

This new potassium beryllium silicate resulted from a high temperature and high pressure synthesis. It has a framework structure built from trimers of silicate tetrahedra and edge-sharing Be-O tetrahedra, and possesses one-dimensional channels along the b axis.

Reinvestigation of Crystalline Sulfuric Acid and Oxonium Hydrogensulfate

The structure of H₂SO₄ consists of H₂SO₄ molecules connected by hydrogen bonds to form 4⁴ nets. In (H₃O)(HSO₄), hydrogen bonding results in the formation of double layers consisting of (HSO₄)_n chains linked by (H₃O) ions.

(NH₄)₂(VO)(VP)O₇, a Layered Structure Comprising Tetrahedral VPO₇ Groups

(NH₄)₂(VO)(VP)O₇ contains [(VO)(VP)O₇]_∞ layers consisting of divanadophosphate VPO₇ groups and VO₅ square pyramids, and layers of NH₄⁺ ions.
