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

S. Vaduvescu and P. G. Potvin

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.
