Abstract
Abstract The reaction of CdCl 2 · 1 2 H 2 O with cinoxacin in DMSO solution affords the [Cd 2 (Cx) 4 (DMSO) 2 ]·2H 2 O dimeric complex ( I ) which has been characterized by single crystal X-ray diffraction; complex II (Cd(Cx) 2 ·H 2 O) was prepared by dissolving I in a minimum amount of water. Compound I is triclinic, space group P 1 with unit cell dimensions: a =8.960(1), b =12.084(5), c =13.696(6) A, α=73.96(4), β=84.69(4), γ=80.93(49)°, V =1405.5(9) A 3 . Each dimer contains cadmium atoms bridged by two carboxylate oxygen atoms from two cinoxacinate (Cx) ligands generating planar Cd 2 O 2 rings. The metal environment is formed by two O carbox and O ceto atoms from the cinoxacinate monoanions, one oxygen atom of the DMSO molecule and a carboxylate oxygen atom which acts as a bridge. One of the coordinated cinoxacinate molecules acts as a bidentate chelate and bridging ligand and the other one as a bidentate chelate ligand. The solid-state IR and 13 C NMR spectra of both compounds are discussed in detail with regard to the crystal structure of complex I .
