The crystal structure of Cd{sub 7}P{sub 4}Cl{sub 6} (I) has been redetermined and of Cd{sub 4}P{sub 2}Cl{sub 3} (KK) solved based on the single crystal X ray diffraction experiments. Crystal data: I, cubic space group Pa3, a = 11.936(1) {angstrom}, z = 4, and R = 0.0226 for 398 independent reflections and 28 refined parameters; II, cubic space group Pa3, a = 12.135(1) {angstrom}, Z = 8, and R = 0.0256 for 466 independent reflections and 29 refined parameters. Both phases crystallize in a space group Pa3, but have quite different crystal structures. The structure of I comprises a three-dimensional cationic net {infinity}{sup 3}[Cd{sub 3}P{sub 2}]{sup 2+} and discrete octahedral anions (CdCl{sub 6}){sup 4{minus}}. The structure of II is based on a fcc packing of cadmium atoms with octahedral and tetrahedral interstices filled with either chlorine or phosphorus atoms or P-P pairs.
