The title compound [Mn(DPMT)2Cl2(H2O)2] (DPMT = 1 -[[2-(2,4-dichlorophenyl)-1,3-dioxolan-2-yl]methyl]-1H-1,2,4-triazole) was synthesized by the reaction of MnCl2-4H2O and DPMT in ethanol solution and its structure was determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P2/c with a=23.913(4), b=7.8883(13), c=8.6291(14) (A),β=95.816(3)°,V=1619.4(5)(A)3,Z=2,C24H26Cl6MnN6O6 Mr=762.15, Dc=1.563 g/cm3, μ=0.950 mm'1, S=1.045, F(000)=774, R=0.0462 and wR=0.0981. The molecular structure is a centrosymmetric conformation, and two ligands are symmetrically located on both sides of the Mn atom. The manganese atom is surrounded by two nitrogen atoms from ligands, two chlorine atoms and two oxygen atoms from water molecules to form a slightly distorted octahedral geometry.
