Abstract
A missed cis isomeric form of a well-known trans-[CuCl2(DMSO)2]n complex has been prepared via the tetranuclear [Cu4Cl8(DMSO)8(hmta)] complex. Structurally, both complexes were found to be molecular i.e. [Cu4Cl8(DMSO)8(hmta)] consists of isolated tetracoordinated hexamethylenetetramine molecules, whereas the cis-complex consists of isolated [(DMSO)2ClCuII(μ-Cl)2CuIICl(DMSO)2] clusters. It should also be noted that the cis-configuration of DMSO molecules in [(DMSO)2ClCuII(μ-Cl)2CuIICl(DMSO)2] was directly transferred from that of [Cu4Cl8(DMSO)8(hmta)], while the trans-[CuCl2(DMSO)2]n isomer was always formed as a final stable product.
