摘要

Extracting residues of an aqueous solutions containing equimolar amounts of K[C(CN)(3)] and RbF or CsF, respectively, with absolute ethanol, yields triangular, transparent colorless crystals of Rb[C(CN)(3)] and Cs[C(CN)(3)] after the ethanol was allowed to evaporate. The compounds are isotypic and crystallize isopointal to calcite in space group R<(3over bar>c (no. 167) with the cell parameters a = 809.9(1) and c = 1461.3(3) pm and a = 843.29(9) and c = 1459.9(2) pm, respectively. Single crystals were used to record the Raman spectra of the title compounds.
