A novel cadmium(II) coordination polymer containing two kinds of independent one-dimensional chain
The structure of the title compound,catena-poly[[cadmium(II)-di-μ-chlorido-μ-(1,4-diazoniabicyclo[2.2.2]octane-1-carboxylato)] [[aquachloridocadmium(II)]-di-μ-chlorido] dihydrate], {[Cd(C8H15N2O2)Cl2][CdCl3(H2O)]·2H2O}n, contains two kinds of independent one-dimensional chain,viz.{[Cd(C8H15N2O2)Cl2]+}nand {[CdCl3(H2O)]−}n, and uncoordinated water molecules. Each CdIIcation in the {[Cd(C8H15N2O2)Cl2]+}nchain is octahedrally coordinated by two pairs of bridging chloride ligands and two O atoms from different bridging carboxylate groups. CdIIcations in the {[CdCl3(H2O)]−}nchain are also octahedrally surrounded by four bridging chloride ligands, one terminal chloride ligand and one coordinated water molecule. Hydrogen bonds between solvent water molecules and these two independent chains generate a three-dimensional framework containing two-dimensional zigzag layers.<!?tpb=18pt>
