Two new complexes, [Mn(L)(mmbda)(H_2O)](1) and [Co(L)(btc)(H_2O)]·H_2O(2), were synthesized by reacting the corresponding metal(Ⅱ) salts with rigid ligand 1,4-di(1Himidazol-4-yl)benzene(L) and two different carboxylic acids of 5-methylisophthalic acid(H_2mmbda) and 1,2,4-benzenetricarboxylic acid(H_3btc), respectively. The structures of the complexes were characterized by single-crystal X-ray diffraction, IR spectroscopy, elemental analysis and PXRD. Complex 1 crystallizes in triclinic, space group P1 with a = 6.9436(4), b = 9.7306(6), c = 15.5302(10) ?, α = 73.7430(10), β = 85.1010(10), γ = 70.0360(10)o, V = 946.75(10) ?~3, Z = 2, C_(21)H_(20)N_4O_5 Mn, M_r = 463.33, D_c = 1.618 g/cm~3, μ = 0.742-1, S = 1.002, F(000) = 474, the final R = 0.0285 and wR = 0.0600 for 4328 observed reflections(I > 2σ(I)). Complex 2 crystallizes in monoclinic, space group P2_1/n with a = 12.5216(12), b = 7.3312(8), c = 22.510(2) ?, β = 93.104(2)o, V = 2063.3(4) ?~3, Z = 4, C_(21)H_(18)N_4O_8Co, M_r = 513.31, D_c = 1.646 g/cm~3, μ = 0.892~(-1) mm, S = 1.096, F(000) = 1044, the final R = 0.0673 and wR = 0.1780 for 3594 observed reflections(I > 2σ(I)). Both of complexes are one-dimensional(1D) chain structures and rich hydrogen bonds extend such 1D chains to form three-dimensional(3D) supramolecular polymers.
