Hydrothermal Synthesis and Crystal Structure of Co(II) Coordination Polymer

A new coordination polymer [Co(BDC)(bimb)](n) (1) with 1,3-benzene dicarboxylic acid (H2BDC) and 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene (bimb) has been has been prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction and EA. Complex, [Co(BDC)(bimb)](n) (1), is triclinic, space group P-1 with a = 8.792 (5), b = 10.076(5), c = 11.767 (5) angstrom, alpha = 85.577(5), beta = 82.481 (5)degrees, gamma = 74.942(5), V = 997.0 (9) angstrom(3), Z = 2, Mr = 461.33, Dc = 1.537 g/cm(3) and F(000) = 474. The final refinement gave R = 0.0411 and wR = 0.0978 for 3634 reflections with I > 2 sigma(I). X-ray diffraction analysis reveals that the complex 1 displays a two-dimensional structure with (4,4)-connected sql topology.
