摘　　要：A new copper（Ⅱ） compound has been prepared and fully characterized by elemen-tal analysis,IR,TG and single-crystal X-ray diffraction.The compound [Cu（4-hba）2（inta）（H2O）]·H2O （4-hba=4-hydroxybenzoic acid,inta=isonicotinamide） 1 crystallizes in the monoclinic system,space group P21/c with a=7.590（5）,b=11.027（5）,c=23.761（5）,β=102.5740（10）o,V=1974.1（16） 3,Mr=991.84,Z=2,Dc=1.669 g/cm3,F（000）=1020,μ=1.166 mm-1,R=0.0353 and wR=0.0604 for 3166 observed reflections （I 〉 2σ（I））.In compound 1,the copper cation is penta-coordinated with two carboxylate oxygen atoms from two different 4-hba ligands,two oxygen atoms from two coordinated water molecules and one nitrogen atom from inta ligand,showing a slightly distorted square-pyramidal geometry.A new copper（Ⅱ） compound has been prepared and fully characterized by elemen-tal analysis,IR,TG and single-crystal X-ray diffraction.The compound [Cu（4-hba）2（inta）（H2O）]·H2O （4-hba=4-hydroxybenzoic acid,inta=isonicotinamide） 1 crystallizes in the monoclinic system,space group P21/c with a=7.590（5）,b=11.027（5）,c=23.761（5）,β=102.5740（10）o,V=1974.1（16） 3,Mr=991.84,Z=2,Dc=1.669 g/cm3,F（000）=1020,μ=1.166 mm-1,R=0.0353 and wR=0.0604 for 3166 observed reflections （I 〉 2σ（I））.In compound 1,the copper cation is penta-coordinated with two carboxylate oxygen atoms from two different 4-hba ligands,two oxygen atoms from two coordinated water molecules and one nitrogen atom from inta ligand,showing a slightly distorted square-pyramidal geometry.
