The assembly of 1,4-benzenedicarboxylic acid (H2bdc), 4,4'-bipyridine (4,4'-bipy), trimethyltin chloride and MnBr2(4H2O in hydrothermal conditions gave rise to a hydrogen-bonded three-dimensional complex {[Mn(4,4'-bipy)(4H2O](bdc)}n which has been characterized by single- crystal X-ray diffraction. The complex crystallizes in the monoclinic system, space group P2/n with a = 7.0001(2), b = 11.5540(3), c = 11.4192(1) A。, β = 101.754(2)o, V = 904.21(4) A。3, Z = 2, C18H20MnN2O8, Mr = 447.30, Dc = 1.643 g/cm3, F(000) = 462 and ((MoKα) = 0.783 mm-1. The final R and wR are 0.0499 and 0.1301, respectively for 1335 observed reflections with I ≥ 2σ(I). The Mn (Ⅱ) is six-coordinated in a distorted octahedral geometry. 4,4'-Bipyridine in a u-bridge mode links [Mn(H2O)4]2+ into a linear cation chain. Bdc acts as a counter anion and links the linear chains into a three-dimensional structure through hydrogen bonds.
