Redetermination of K(4)[Bi(2)Cl(10)]·4H(2)O.

ABSTRACT: In comparison with the previous refinement of tetra-potassium di-?-chlorido-bis-[tetra-chloridobismuthate(III)] tetra-hydrate [Volkova, Udovenko, Levin & Shevchenko (1983). Koord. Khim.9, 356-360], the current redetermination reveals anisotropic displacement parameters for all non-H atoms, localization of the H atoms, and higher precision of lattice parameters and inter-atomic distances. The crystal structure is built up of edge-sharing [Bi(2)Cl(10)](4-) double octa-hedra with the bridging Cl atoms situated on a mirror plane, three K(+) counter-cations (two of which are on mirror planes), and two water mol-ecules that are solely coordinated to the K(+) cations. These building units are linked into a three-dimensional network structure. Additional O-H?Cl hydrogen bonds between the water mol-ecules and the complex anions stabilize this arrangement.
