Synthesis and Single Crystal X-Ray Structure Determination of 3,3',5,5'- tetramethyl-4,4'-bipyrazolium tetrachloromanganate(II) monohydrate ([H2Me4bpz]2[MnCl4]Cl2·H2O)

MA Kurawa, AG Orpen

Abstract


The title compound was synthesized mechanochemically by grinding MnCl2.4H2O and the protonated organic ligand [H2Me4bpz] resulting in the formation of [H2Me4bpz][MnCl4]. Suitable single crystal of this compound was analysed through X-ray diffraction technique to ascertain its composition and internal structure. Single crystal structure determination at 100 K revealed needle-like crystals in an orthorhombic crystal system. The asymmetric unit of the cell consists of an isolated chloride ion, one half of a tetrahedral [MnCl4]2- anion, a [H2Me4bpz]2+ dication and one half of a molecule of water.
