Bis(3,5-dimethyl-1H-pyrazole-κN2)bis(3,3′′,5,5′′-tetramethyl-[1,1′:3′,1′′-terphenyl]-2′-carboxylato-κO)iron(II) dichloromethane monosolvate

Abstract

In the title compound, [Fe(C23H21O2)2(C5H8N2)2]·CH2Cl2, the Fe2+ cation is coordinated by the N atoms of two 3,5-dimethylpyrazole ligands and the carboxylate O atoms from two tetramethylterphenylcarboxylate ligands, forming an FeN2O2 polyhedron with a slightly distorted tetrahedral coordination geometry. Intramolecular N—H...O and C—H...O hydrogen-bonding interactions stabilize the molecular conformation. The dihedral angles formed by the central benzene ring with the outer benzene rings of the terphenyl groups are 47.92 (8), 59.38 (8), 48.24 (8) and 52.37 (8)°. The dichloromethane solvent molecule interacts with the complex molecule via a C—H...O hydrogen bond. In the crystal, centrosymmetrically related complex molecules are linked into dimers through pairs of C—H...O hydrogen bonds.
