Abstract
A new coordination polymers{[Co(2,4'-opb)(bimb)]·H2O}n (1) (2,4'-opb = 2-(4'-carboxy-phenoxy)benzoic acid, bimb = 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene), has been prepared by hydrothermal synthesis. Complex [Co(2,4'-opb)(bimb)]n (1), is monoclinic, space group P21/c with a = 11.473 (5) Å, b = 11.905 (5) Å, c = 18.899 (5) Å, b =100.872° V = 2535.0 (15) Å3, Z = 4, Mr = 571.44, Dc = 1.497 g/cm3, F(000) = 1180 and μ = 0.73 mm-1. The final refinement gave R = 0.0305 and wR = 0.0831 for 5110 reflections with I > 2s (I). X-ray diffraction analysis reveals that complex 1 shows a three-dimensional supramolecular structure based on a two-dimensional (4,4) sql layer.
