The First Example Of A Bis-Monohelical Complex: The Crystal And Molecular Structure Of [Mn-2(Dmqpy)(2)(H2o)(2)(Mu-Cl)][Clo4](3)Center Dot 4h(2)O (Dmqpy=6,6''''-Dimethyl-2,2':6',2'':6'',2''':6''''-Quinquepyridine)

6,6''''-Dimethyl-2,2':6',2 '' 6 '',2'''': 6''',2''''-quinquepyridine (dmqpy) is found to form a dinuclear 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.
