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

초록

In the title compound, [Fe(C23H21O2) 2(C5H8N2)2] ·CH2Cl2, the Fe2+ cation is coordinated by the N atoms of two 3,5-dimethyl-pyrazole ligands and the carboxyl-ate O atoms from two tetra-methyl-terphenyl-carboxyl-ate ligands, forming an FeN 2O2 polyhedron with a slightly distorted tetra-hedral coordination geometry. Intra-molecular N - H⋯O and C - H⋯O hydrogen-bonding inter-actions 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 dichloro-methane solvent molecule inter-acts 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. © Jeon et al. 2012.
