摘要：

The crystal and molecular structure of [Co(cp2qpy)(MeOH)(H2O)][PF6]2 (cp2qpy = 4',4'''-bis(4-chlorophenyl)-2,2': 6',2":6",2''':6''',2''''-quinquepyridine reveal the cation to be a mono-helical seven-coordinate species [P2(1)a, a = 17.441(4), b = 11.765(4), c = 20.402(6) angstrom, beta = 105.24(2)-degrees] unlike 2,2': 6',2":6",2''':6''',2''' quinquepyridine (qpy), which forms a double-helical 2:2 complex with cobalt(II), [CO2(qpy)2(OAc)]3+; in acetonitrile solution the qpy and cp2qpy complexes give rise to common mononuclear species.
