• A discrete dicopper(ii) system, [Cu(bipy)(H sub(2)mpba)] sub(2).2H sub(2)O (1), and its isomeric chain, [Cu(bipy)(H sub(2)mpba)].dmso (2) [bipy = 2,2'-bipyridine and H sub(4)mpba = N,N'-1,3-phenylenebis(oxam ic acid)], were obtained by modifying the ratio of the H sub(2)O-dmso solvent mixture, and their interconversion was also monitored by changing the solvents during the synthesis. The solvents play an essential role in the formation and crystallization of these complexes, presenting different dimensionalities and connectivities. The double deprotonated H sub(2)mpba super(2-) adopts the bidentate/monodentate (1) and bis-bidentate (2) bridging modes toward the (2,2'-bipyridyl)copper(ii) units affording a dinuclear compound (1) and a linear chain (2), respectively. Variable-temperature magnetic measurements show the occurrence of weak intradinuclear (1) and intrachain (2) antiferromagnetic interactions.
