The synthesis, characterizations and crystal structures for [Cu(ipnm)(hmpH)] (1), mixed-valent tetranuclear [MnII 2MnIII 2(dcnm)2(hmp)6Cl2] (2) and the homo-valent hexanuclear [FeIII 6(dcnm)6(hmp)8O2] (3), (where ipnm = imido[cyano (picolinoyl)methyl]nitrosomethanide, hmpH = 2-hydroxymethylpyridine; dcnm = dicyanonitrosomethanide) are reported. The formation of new dianionic ligand, ipnm which is also an imide derivative, represents the scarce example of metal-mediated in-situ dehydrogenative cross-coupling between amide derivatives with primary alcohol. Structure of 2 is known as ‘butterfly’ type structure while hexanuclear cluster 3 exists in chair-like conformation which in both structures, the dcnm acting as a terminal ligand.
