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

Abstract

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.
