Brown crystals of title compound, bis(methyl-2-pyridylmethylidene-drazinecarbodithioate)manganese(II), was formed by reaction of methyl-2-pyridylmethylidenehydrazinecarbodithioate(HNNS) with manganese perchlorate at 323 K temperature and recrystallized from ethanol at room temperature, crystallizing in the monoclinic system, space group P 2(1)/n, with a  = 11.631(2), b  = 14.010(3), c  = 13.128(3) Å, β  = 105.791(11)°; V  = 2058.6(7)  Å 3 , D c  = 1.533 g/cm 3 , Z  = 4, C 16 H 16 N 6 MnS 4 , M r  = 475.53, μ(M 0   K α ) = 1.060 mm −1 , F (000) = 972. The structure was refined to R  = 0.0441, wR  = 0.1196 for 3,682 ( I  > 2σ( I )) reflections and S = 1.110. In title complex the coordination geometry about manganese is distorted octahedral and the two ligands in the mer configuration (S and tertiary N atom cis to each other and the iminic N atoms trans ). Furthermore, the neutral molecule units Mn II (NNS) 2 are connected by hydrogen bonds C–H···N and C–H···S and form a three dimensional ordered network structure. Graphical Abstract The title compound, Mn(NNS) 2 , exists as discrete molecules in which the central MnII atom is coordinated by two S atoms and four N atoms from two ligands NNS- molecules in a mer-octahedral configuration.
