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.
