μ-Phenolato-μ-chlorido-bridged Dinuclear Manganese(II) Complex with a Dinucleating Schiff-base Ligand Having Imidazolyl Groups

Abstract

in A μ -phenolato- μ -chlorido-bridged dinuclear manganese(II) complex with 2,6-bis( N -(4-imidazolylethyl)iminomethyl)-4-methylphenol (Hbimmp), [Mn 2 (bimmp)( μ -Cl)Cl 2 ], was isolated. The crystal structure was determined by a single-crystal X-ray diffraction method at 293 K. The complex crystallizes in the orthorhombic space group F dd2 with a = 40.557(4), b = 9.2353(9), c = 12.5138(2)Å, V = 4687.1(8)Å 3 , D calcd = 1.603 g/cm 3 , Z = 8. The R 1 [ I > 2 σ ( I )] and wR 2 (all data) values are 0.0309 and 0.0826, respectively, for all 2683 independent reflections. The two manganese(II) atoms are bridged by a phenolato-oxygen of bimmp – and a μ -chlorido atom, where each manganese(II) atom is further coordinated by imino- and imidazolyl-nitrogen atoms of bimmp – and chlorido atoms to form a square-pyramidal geometry.
