摘要
The title compound, Co（L）2（CH3OH）2Cl2 （L = 3-（1,2,4-triazole-yl）-6-chloro-pyridazine） 1, has been synthesized and its crystal structure has been determined by X-ray analysis. Complex 1 crystallizes in the triclinic system, space group P1 with a = 6.018（3）, b = 9.832（5）, c = 9.921（5）A, a = 78.270（8）, β = 74.550（8）, γ = 83.807（8）°, V = 553.1（5）A^3, Z = 1, C14H16Cl4CoN10O2, Mr = 557.10, Dc = 1.673 g/cm^3, F（000） = 281,μ（MoKα） = 1.293 mm^-1, the final R = 0.0453 and wR = 0.1181 for 1539 observed reflections with I 〉 2σ（I）. The Co（II） ion is in a distorted centrosymmetric six-coordinate octahedral environment with two Ntriazole, two Omethanol and two Cl atoms. Via hydrogen bonds the configuration of 1 has been extended into 1D chains which are developed to 2D layers via π-π sticking action, and these layers are further extended into a 3D network by hydrogen bonds. The antibacterial activity of the title compound has been detected, and the results show that the ligands and cobalt（II） complex exhibit certain fungicidal activity against several bacteria. Furthermore, the spectral properties of the title compound have been also studied and discussed.
