Abstract
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 P2(1)/n, with a = 11.631(2), b = 14.010(3), c = 13.128(3) Å, β = 105.791(11)°; V = 2058.6(7) Å3, D c = 1.533 g/cm3, Z = 4, C16H16N6MnS4, M r = 475.53, μ(M0 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 MnII(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.
