One cadmium(Ⅱ)coordination polymer [Cd(phen)(4,6-dimethyl-5-nitro-isophtha-lic acid)]n(1)has been synthesized with 4,6-dimethyl-5-nitro-isophthalic acid,phen(phen = 10-phenanthroline),and cadmium nitrate in the mixture of DMSO:H2O(V:V = 2:1).Crystallogra-phic data for this complex:monoclinic,space group P21/c,with a = 11.668(2),b = 11.841(6),c = 14.446(2),β = 102.440(4)°,V = 1.9491(8)3,Dc = 1.805 g/cm3,Z = 1,F(000)= 1056,GOOF = 0.999,R = 0.0280 and wR = 0.0662.The crystal structure analysis indicates that the cadmium ion is coordinated with two nitrogen atoms of one 1,10-phenanthroline molecule and five oxygen atoms from three 4,6-dimethyl-5-nitro-isophthalic acid molecules.The curve of TGA shows that 1 is stable up to 380.0 ℃.

The crystal structure analysis indicates that the cadmium ion is coordinated with two nitrogen atoms of one 1,10-phenanthroline molecule and five oxygen atoms from three 4,6-dimethyl- 5-nitro-isophthalic acid molecules. The curve of TGA shows that 1 is stable up to 380.0 ° C.
