A novel NiⅡ complex {[Ni(IBG)(μ-H2O)(H2O)2]·2H2O}n 1(H2IBG = isophthaloylbisglycine) has been synthesized and characterized by single-crystal X-ray diffraction,elemental analysis,IR spectra,and thermogravimetric analysis.It crystallizes in monoclinic,space group P2/c with a = 15.40(2),b = 6.960(10),c = 7.865(11) ,β = 90.32(3)o,V = 843(2) 3,Z = 2,C12H18NiN2O11,Mr = 424.99,Dc = 1.675 g/cm3,F(000) = 440,μ(MoKα) = 1.214 mm-1,the final R = 0.0514 and wR = 0.1247 for 1078 observed reflections with I > 2σ(I).In the structure,each NiⅡcenter is situated in the center of a rather regular octahedron.Moreover,thermal stability has been studied and magnetic measurements show antiferromagnetic interactions for this complex.
