title: A novel mixed-valence complex containing Co(II)(2)Co(III)(2) molecular squares with 4,5-imidazoledicarboxylate bridges.
abstract: A heterometallic complex, Na(2)[Co(II)(2)Co(III)(2)(IDC(3-))(4)(bipy)(4)].12H(2)O (bipy = 2,2'-bipyridine), in which mixed-valence tetranuclear squares with imidazoledicarboxylate (IDC(3-)) linkers are tethered into a unique chain through disodium units, is hydrothermally synthesized and structurally and magnetically characterized.
