Abstract

In comparison with the previous refinement of tetrapotassium di-μ-chlorido-bis[tetrachloridobismuthate(III)] tetrahydrate [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 interatomic distances. The crystal structure is built up of edge-sharing [Bi2Cl10]4− double octahedra with the bridging Cl atoms situated on a mirror plane, three K+ counter-cations (two of which are on mirror planes), and two water molecules 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 molecules and the complex anions stabilize this arrangement.
