A monoclinic polymorph of uranyl dinitrate trihydrate, [UO2(NO3)2(H2O)2]·H2O

R. R. Shuvalov and P. C. Burns

Synopsis: The main building block of the crystal structure of monoclinic [UO2(NO3)2(H2O)2]·H2O is the finite non-centrosymmetric [UO2(NO3)2(H2O)2] cluster, which is a uranyl hexagonal bipyramid that shares two non-opposite equatorial edges with the nitrate triangles, such that the two water molecules are at neighbouring equatorial vertices. There is an interstitial water site in the structure, which is located between adjacent [UO2(NO3)2(H2O)2] clusters.

Formula: [UO2(NO3)2(H2O)2]·H2O

(K4Li4)Al8Ge8O32·8H2O: an Li+-exchanged potassium aluminogermanate with the zeolite gismondine (GIS) topology

A. J. Celestian, J. B. Parise, A. Tripathi, Å. Kvick and G. M. B. Vaughan

Synopsis: The title microporous material, (K,Li)-(Al,Ge)-GIS, namely lithium potassium dialuminium digermanium octaoxide dihydrate, is the result of a 50% Li+ exchange into the K-(Al,Ge)-GIS structure. A structural change occurs due to disordering of K+ ions with Li+ ions along [001] and ordering of water molecules along [101].

Manganese antimony diselenide iodide, MnSbSe2I

O. Tougait, J. A. Ibers and A. Mar

Synopsis: Manganese antimony diselenide iodide is a distorted variant of the UFeS3 structure. The structure contains layers parallel to the bc plane that consist of edge- and corner-sharing MnSe6/2 and MnSe2/2I4/2 octahedra. Sb atoms are located between these layers and form SbSe3 trigonal pyramids.

Formula: MnSbSe2I

Two modifications of a KH2PO4·HF adduct

R. Krupková, J. Fábry, P. Vanek and I. Císarová

Synopsis: The refinements of two modifications of an adduct of potassium dihydrogenphosphate and hydrofluoric acid were performed on data collected at 250 and 150 K, and at 292 and 150 K. Both modifications contain a very short F-H...O hydrogen bond. The modifications differ in the arrangement of the dihydrogenphosphate anions and the hydrogen-bonding schemes.

Formula: KH2PO4·HF

W. Massa, O. V. Yakubovich and O. V. Dimitrova

Synopsis: A new cubic form, in space group F\overline 43m, of Cs[Mg(H2O)6](PO4) has been found and is isostructural with the analogous arsenate. [Mg(H2O)6]2+ cations and phosphate anions are connected by hydrogen bonds, forming a sphalerite-like three-dimensional framework.

J. H. Yang, W. K. Choo and C. H. Lee

Synopsis: The room-temperature structure of the B-site-ordered complex perovskite dicalcium magnesium tungstate, Ca2MgWO6, has been determined by simultaneous Rietveld refinement of neutron and X-ray powder diffraction patterns. Ca2MgWO6 is characterized by B-site ordering and an a-a-c+-type BO6 octahedral tilt mechanism.
