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-dimethyl­pyrazole ligands and carboxyl­ate O atoms from two 4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxyl­ato ligands, forming an MnN(2)O(2) polyhedron with a slightly d...

Sumario: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-dimethyl­pyrazole ligands and carboxyl­ate O atoms from two 4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxyl­ato ligands, forming an MnN(2)O(2) polyhedron with a slightly distorted tetra­hedral coordination geometry. Two intra­molecular hydrogen bonds are observed between the carboxyl­ate and pyrazole ligands. The combined influence of the sterically hindered carboxyl­ate ligands and the intra­molecular hydrogen-bonding inter­actions 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.
