Me4en or dipn). The structures of 1−6 consist of cationic tetranuclear CuII2MII2 entities with an overall 4R rack-type architecture, which is made up of two oxamato-bridged homo- (1−5) or heterodinuclear (6) CuIIMII units (M = Cu and Ni) connected through either a meta- (1, 2, and 4) or a para-substituted (3, 5, and 6) phenylene spacer between the CuII ions.
