Two complexes (H2bipy)[M2(TB)2(H2O)8]·5H2O (M = Mn 1, Zn 2) (bipy = 4,4′-bipyridine, H3TB = 1,3,5-tris(carboxymethoxyl)benzene) were synthesized by the reaction of the corresponding metal salt with ligand H3TB and 4,4′-bipy in an aqueous methanol solution at room temperature, respectively. Their structures were determined by single crystal X-ray diffraction analysis. Both complexes 1 and 2 crystallize in the triclinic space group \(P\bar 1\) with the crystal parameters of 1: a = 9.725(12) Å, b = 10.651(13) Å, c = 10.882(13) Å, α = 91.72(2)°, β = 96.41(2)°, γ = 97.72(2)°, V = 1109(2) Å3, Z = 1 and 2: a = 9.610(10) Å, b = 10.55(2) Å, c = 10.83(2) Å, α = 91.60(4)°, β = 95.32(2)°, γ = 97.73(4)°, V = 1082(3) Å3, Z = 1. Complexes 1 and 2 have the same dinuclear structure, in which each metal atom is six coordinated with distorted octahedral geometry by two oxygen atoms from two different TB3− ligands and four ones from four coordinated water molecules. The dinuclear units are further linked by hydrogen bonding and π–π interactions to form the three-dimensional framework structure.
