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

By Sivanesan Dharmalingam, Yeojin Jeon and Sungho Yoon


In the title compound, [Mn(C19H11F2O2)2(C5H8N2)2], the Mn2+ 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 MnN2O2 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
