AbstractThe mixed-anion polymeric complex {[Cd(Ph(3)P(CH2)(2)CO2)(H2O)(mu-Cl)(2) CdCl(Ph(3)P(CH2)(2)CO2)(H2O)(2)]ClO4}(n) (1) the coordination geometries of the two independent cadium(II) atoms Cd(1) and Cd(2) are distorted CdCl2O4 and CdO3Cl3 octahedra, respectively. Cd(1) is asymmetrically chelated by a Ph(3)P(+)(CH2)(2)CO2- ligand (L), Cd(2) is monodentately coordinated by another ligand L, the two cadmium atoms are joined by a pair of chloride bridges and the remaining coordination positions are occupied by two aqua ligands and a terminal chloride. The asymmetric units are syn-anti bridged by the monodentate ligand L to form a polymeric chain extending parallel to [1(1) over bar0$] and such chains are cross-linked by donor hydrogen bonds from the aqua ligands to the terminal chlorides and oxygen atoms of the chelating L ligands to form a positively charged layer with Ph(3)P groups protruding on both sides. The interlayer separation is c/2 and the perchlorate anions are sandwiched between adjacent layers. Copyright 1996 Elsevier Science Ltd
