| Abstract: A dinuclear Mn(Ⅱ) complex [Mn2L2(μ-Cl)2Cl2(H2O)2] (1) was synthesized by reaction of ligand L with MnCl2 ·4H2O and its structure was determined by X-ray crystal structure analysis. The structure indicates that the complex crystallizes in monoclinic, space group C2/c with a=2.018 0(15) nm, b=0.894 0(6) nm, c=1.932 1(14) nm, β=97.506(12)°. V=3 456(4) nm3, Z=4, Dc=1.515 Mg·m-3, μ=1.081 mm-1, F(000)=1 608, and final R1=0.043 8, wR2=0.109 9. The result shows a Mn(Ⅱ) ion was six-coordinated by a bidentate 3-methyl-4-( p-methylphenyl)-5-(2-pyridyl)-1,2,4-triazole, one chlorine and one bridging chlorine atom in the basal positions and one chloride atom and one water molecule in the axial one, to form a distorted octahedral-pyramidal geometry.
