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. |
