Synthesis and Crystal Structure of Cadmium Dodecahydro closo-Dodecaborate
Hexahydrate, Cd(H2O) 6[B 12H12 ]. ? Single crystals of the title compound are prepared by neutralization of an aq. solution of (H3O)2[B12 H12] with excess CdCO3 at
80 ░C. Cd(H2O) 6[B12H12] crystallizes in the monoclinic space group C2/m with Z = 4.
The structure can be regarded as a monoclinic distortion variant of the CsCl-type structure. Two crystallographically different [Cd(H2O) 6]2+ octahedra are present which only
differ in their relative orientation.The hydrogen atoms of the [B12H12]2- clusters have no
direct coordinative influence on the Cd2+ cations. The lattice is stabilized by
B?H?-иии+?H?O hydrogen bonds. ? (TIRITIRIS, I.; SCHLEID*, T.; Z. Anorg. Allg.
