Bis(homoleptic) vs. heteroleptic copper(I) complexes: Electrosynthesis, spectroscopy, and crystal structure of Cu(BIK)2+2Cu4(SR)62-·3(CH3CN)·(RSH); BIK = bis(2-methylimidazol-2-yl)ketone, R = o-tolyl
Anodic oxidn. of Cu in MeCN/2mM Bu4NClO4 and in the presence of bis(N-methylimidazol-2-yl)ketone (BIK) and excess o-thiocresol RSH yields the title compd. as the main product. Whereas the dianionic cluster Cu4(SR)62- is similar to such previously reported species with R = Ph or Me, the purple cations Cu(BIK)2+ exhibit spectroscopic and structural effects of p back bonding between electron-rich Cu(I) and the p acceptor ligand BIK. In contrast to the formally related Zn(BIK)22+, the Cu(I) complex cations exhibit distorted tetrahedral structures with almost coplanar BIK chelate arrangements which ensures max. metal-ligand p interaction. on SciFinder(R)
