Cadmium copper tetrachloride tetrahydrate

The double salt [CuCl2(H2O)(2)(CdCl2)]. 2H(2)O crystallizes in the triclini c rather than the monoclinic system as reported previously. The structure c onsists of sheets in the ac plane with slightly distorted octahedral CdCl6 [Cd-Cl 2.5813(8)-2.6943 (8) Angstrom] connected by Cd-Cl-Cd bridges in the Cd equatorial plane along a, and by Cd-Cl-Cu bridges to layers of square-pl anar CuCl2(H2O)2 along c, There are long axial Cu-Cl interactions of 2.8623 (7)Angstrom and additional water of hydration is hydrogen bonded to coordi nated water and chloride ligands. The additional water connects the ne shee ts into a three-dimensional network, Both Cd and Cu occupy different P (1) over bar sites, The Cu...Cu and Cd...Cd distances are 3.8274 (6) Angstrom.
