A one-dimensional chain coordination polymer [Cu(phen)(2,4,6-TMBA)(2)(H2O)](n) has been synthesized by reacting 2,4,6-trimethyl-benzoic acid, 1,10-phenanthroline and Cu(II) perchlorate and its structure was characterized. Crystal data for this complex: tetragonal, space group 14(1), a = 2.0293(3), b = 2.0293(3), c = 1.3758(2) nm, alpha = beta = gamma = 90 degrees, V = 5.6657(13) nm(3), D-c= 1.379 g/cm(3), Z = 8, mu(MoK alpha) = 0.815 mm(-1), M-r = 588.14, F(000) = 2456, S = 1.047, R = 0.0459 and wR = 0.1053. The crystal structure shows that two neighboring Cu(II) ions are linked together by on...
