A pair of chiral 2,2':6',2'': 6'',2'''-quaterpyridine ligands 1 and 2 have been prepared and shown to diastereoselectively assemble double-helical coordination compounds. The complexation of 1 or 2 with copper(i) or silver(i) leads to dinuclear double helicates [M 2 (L) 2 ] 2 with high diastereosele
The title compound, C 20 H 14 N 4 , shows dimorphism, with crystals obtained from different solvents displaying different crystal structures. The main structural difference between the two polymorphs concerns the crystal packing, the dihedral angle between two nearly planar molecules being distinctl
