The first example of a bis-monohelical complex: the crystal and molecular structure of [Mn2(dmqpy)2(H2O)2(µ-Cl)][ClO4]3·4H2O (dmqpy = 6,6â�—-dimethyl-2,2′ : 6′, 2″ : 6″,2‴ : 6â�—-quinquepyridine)
Abstract
6,6â�—-Dimethyl-2,2′ : 6′,2″ 6″,2â�— : 6‴2â�—-quinquepyridine (dmqpy) is found to form a dinculear complex with manganese(II), the structure of which is not double helical but composed of two shallow monohelical complex cations bridged by a chloride ion.
