The title compound {[Mn(H2BPTC)(tpy)(H2O)]·(H2O)3}n (1, H4BPTC = 1,1′- biphenyl-2,2′,6,6′-tetracarboxylic acid, tby = 2,2′:6,2′′-terpyridine) has been synthesized by the hydrothermal reaction, and its structure was determined by X-ray diffraction and characterized by elemental analysis, IR spectrum and thermogravimetric analysis. The crystal is of monoclinic, space group P21/c with a = 10.971(2), b = 20.776(4), c = 14.332(3) , β = 109.25(3)o, MnC31H27N3O12, Mr = 688.50, V = 3084.1(10) 3, Dc = 1.483 g/cm3, F(000) = 1420, μ = 0.498 mm-1, S = 1.066 and Z = 4. The final refinement gave R = 0.0447 and wR = 0.1103 for 5107 observed reflections with I > 2σ(I). The title complex has a {[Mn(H2BPTC)(tpy)(H2O)]}n chain structure, and the hydrogen bonding interactions make it more stable. Each chain is further connected to the adjacent ones through π···π, C-H···π and rich hydrogen bonds to form a metal-organic coordination polymer.
