摘 要: | In the past three decades, more than one hundred polynuclear Cu(I) complexes, organometallics and clusters have been synthesized[1]. In many of these compounds there are relatively short Cu-Cu distances of 0.238—0.32 nm (Cu-Cu in metal 0.240 nm). Since Cu(I) has a closed d10 electronic sub-shell, the nature of d10-d10 interactions has also been studied theoretically[2], but the problem whether there is direct or no direct covalent Cu-Cu bonding is still not clear. The same situation also …
