Bis(4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxyl­ato-κO)bis­(3,5-dimethyl-1H-pyrazole-κN 2)manganese(II)


In the title compound, [Mn(C(19)H(11)F(2)O(2))(2)(C(5)H(8)N(2))(2)], the Mn(2+) cation is coordinated by the N atoms of two 3,5-dimethyl-pyrazole ligands and carboxyl-ate O atoms from two 4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxyl-ato ligands, forming an MnN(2)O(2) polyhedron with a slightly distorted tetra-hedral coordination geometry. Two intra-molecular hydrogen bonds are observed between the carboxyl-ate and pyrazole ligands. The combined influence of the sterically hindered carboxyl-ate ligands and the intra-molecular hydrogen-bonding inter-actions stabilizes the title compound with a low coordination number of four. In the crystal, weak C-H⋯F and C-H⋯O hydrogen bonds are observed.
