One novel binuclear cadmium(Ⅱ) Complex [Cd_2(phen)_2(C_(15)H_(11)O_3)_4 ]·(H_2O) with o-methylbenzoyl-benzoic acid and 1,10-phenanthroline(phen) has been synthesized by means of hydrothermal way and characterized.It was characterized as crystallizing in the Triclinic space group P1,with a= 1.1155(2)nm,b= 1.2069(2)nm,c= 1.4355(3) nm,α=99.79(3)°,β=111.27(3)°,γ=98.17(3)°,V=1.730 5(6) nm~3,D_c=1.514 g·cm~(-3),Z=1,F(000)=804.Final GooF=1.060,R_1=0.024 7,wR_2=0.063 2.The crystal structure shows that the cadmium ion is coordinated with four oxygen atoms from three o-methylbenzoyl-benzoic acid radical,two nitrogen atoms from one 1,10-phenanthroline molecule,forming a distorted octahedral coordination geometry.There exist two coordination types with the o-methylbenzoyl-benzoic acid,which coordination with the center cadmium ion with the bridging and chelating bidentatein types.Two o-methylbenzoyl-benzoic acid molecules and two cadmium(Ⅱ) ions form a octatomic ring stable under 220.0℃.CCDC:741934.
