1,3-Bis(2,2′:6′,2′′-terpyridin-4′-yl)benzene, a new dinucleating bis(tridentate) ligand, as its dichloromethane solvate

Abstract

The title compound, 1,3-bis(2,2′:6′,2′′-terpyridin-4′-yl)­benzene di­chloro­methane solvate, C36H24N6·CH2Cl2, is a new ligand suitable for bridging two metal centres. Though not in binding conformations, its two ter­pyridine units are linked in a unique arrangement, through a meta-phenyl­ene core, which disallows resonance communication between binding sites, as reflected by the crystal structure of its 1:1 CH2Cl2 solvate. The two ter­pyridine units are related by crystallographically imposed twofold symmetry, forming a 30.02 (8)° dihedral angle with the phenyl­ene core, but with fairly coplanar pyridine rings within. The solvent mol­ecule is disordered over the twofold axis.
