In the title compound, [Fe(C(23)H(21)O(2))(2)(C(5)H(8)N(2))(2)]·CH(2)Cl(2), the Fe(2+) 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(2)O(2) polyhedron with a slightly distorted tetra-hedral coordination geometry. Intra-molecular N-H⋯O and C-H⋯O hydrogen-bonding inter-actions stabilize the mol-ecular 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 mol-ecule inter-acts with the complex mol-ecule via a C-H⋯O hydrogen bond. In the crystal, centrosymmetrically related complex mol-ecules are linked into dimers through pairs of C-H⋯O hydrogen bonds.
