Bis(4,4′′-difluoro-1,1′:3′,1′′- terphenyl-2′-carboxylato-κO)bis(3,5-dimethyl-1H-pyrazole- κN2)manganese(II)

초록

In the title compound, [Mn(C19H11F2O 2)2(C5H8N2)2], the Mn2+ 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 MnN2O2 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. © Dharmalingam et al. 2012.
