Synopsis: The crystal structure of the sanidine feldspar analogue potassium iron germanate, quenched from 873 K, has been determined in the C2/m space group using a flux-grown single crystal. A partial ordering of Fe is observed on the two tetrahedral sites, with a preferential occupancy for the T1 site (32%) over the T2 site (18%). This ordering is also reflected by the difference in the size of the tetrahedral sites [mean <<span class="it">T1-O> 1.765 (2) Å versus <<span class="it">T2-O> 1.749 (2) Å].
Formula: KFeGe3O8

Synopsis: The structure of bis(1,2-ethanediammonium) dichloride tetrachloromercurate, originally determined at 153 K [Wen et al. (1992). Inorg. Chim. Acta, 193, 77-85], has been redetermined with room-temperature data carefully corrected for absorption effects.
Formula: (C2H10N2)2Cl2[HgCl4]
Acta Cryst. (1998). C54, IUC9800035 [ doi:10.1107/S010827019809948X ]
Synopsis: This compound was isolated as a deactivation product from olefin metathesis polymerization and its crystal structure was determined. The W atom has a square-pyramidal coordination geometry with the phenylimido ligand occupying the apical position. A relatively short W-N(imido) bond, 1.736 (3) Å, is interpreted as arising from the interaction of the lone pair of N(imido) and the W metal center.
Formula: [W(C4H8)(C6H5N)(C12H22N2Si2)]
