摘　　要：A novel binucleus mixed-ligand[Cd2(phen)4(bmal)2]·3H2O (phen=phenanthroline; bmal=benzylmalonic acid radical) has been synthesized by the reaction of phen and bmal with cadmium(Ⅱ) salt. X-ray crystal structure analysis was carried out to determine the crystal structure of the title complex. The crystal of the title complex belongs to monoclinic system with space group P21/c, a=1.119 1(8) nm, b=2.480 5(17) nm, c=1.063 4(8) nm, β=142.042(12)°, Z=4, V=2.887(3) nm3, Dc=1.613 g·cm-3, R1=0.046 2, wR2=0.115 6, F(000)=1 424. One carboxyl of bmal is coordinated to Cd(1) with monodentate form, the others are coordinated to Cd(2) with bidentate form. The complexes form a 1-D chain structure bridged by hydrogen bonds that formed by uncoordinated water and oxygen atom of carboxyl group in bmal, the 2-D network structure was formed by π-π interaction of neighbouring phen. CCDC: 257080.A novel binucleus mixed-ligand[Cd2(phen)4(bmal)2]·3H2O (phen=phenanthroline; bmal=benzylmalonic acid radical) has been synthesized by the reaction of phen and bmal with cadmium(Ⅱ) salt.
