Two cadmium(Ⅱ) compounds linked by a flexible dipyridyl ligand {[Cd2(Hbpma) Cl5(H2O)]·2H2O}n 1 and [Cd(Hbpma)Cl(H2O)2]2·2SO4·3H2O 2 (bpma = N,N-bis(3-pyridylmethyl)amine) have been synthesized and structurally characterized by single-crystal X-ray diffraction. Complex 1 crystallizes in triclinic, space group P with a = 9.5612(6), b = 11.3401(7), c = 11.5069(12), α = 112.8540(10), β = 106.5330(10), γ = 101.6680(10)°, V = 1030.77(14)3, C12H20Cd2Cl5N3O3, Mr = 656.36, Z = 2, Dc = 2.115 g/cm3, μ(MoKα) = 2.727 mm-1, F(000) = 636, S = 1.059, the final R = 0.0319 and wR = 0.0822 for 3443 observed reflections (I > 2σ(I)). For complex 2, it belongs to triclinic, space group P with a = 10.9487(4), b = 11.4197(4), c = 15.4288(5), α = 94.7470(10), β = 104.1000(10), γ = 104.42°, V = 1790.76(11)3, C24H42Cd2Cl2N6O15S2, Mr = 1014.46, Z = 2, Dc = 1.881 g/cm3, μ(MoKα) = 1.529 mm-1, F(000) = 1020, S = 1.050, the final R = 0.0178 and wR = 0.0451 for 6026 observed reflections (I > 2σ(I)). Complex 1 is found to have tetranuclear Cd(Ⅱ) clusters which are bridged by the protonated bpma ligands leading to one-dimensional coordination polymers, whereas complex 2 consists of binuclear Cd(Ⅱ) structures linked by the protonated bpma ligands. Both complexes are assembled into three-dimensional supramolecular structures through hydrogen bonding interactions.
