Synthesis and Crystal Structure of a New Cadmium(II) Polymer with One-dimensional Chain Structure:[Cd(5-hip)(phen)]_n·nH_2O (5-hip=5-Hydroxyisophthalate,phen=1,10-Phenanthroline)

A new metal-organic coordination polymer [Cd(5-hip)(phen)]n·nH2O 1 has been hydro-ermally synthesized and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction. The crystal of the complex crystallizes in monoclinic, space group P2/n with a = 8.8071(17), b =12.386(2), c = 16.981(3) , β = 100.182(2)°, V = 1823.2(6) 3, Mr = 490.73, Dc = 1.788 g/cm3, μ(MoKa) = 1.240 mm-1, F(000) = 976, Z = 4, the final R = 0.0458 and wR = 0.1373 for 2864 observed reflections (I 2σ(I)). The Cd atoms are coordinated by two N atoms from the phen ligands and four O atoms from 5-hydroxyisophthalate ligands in a highly distorted octahedral geometry.
