In several derivatives [49,56,77,93,119,120,143] two crystallographically independent molecules are present in the same crystal, and in two cases [41,76] Table 11, where several relationships, as discussed individually in each chapter, may be observed. The M-M bond lengths are summarised in Table 12, where the variety of metals which can interact with the soft copper(I) atom can be seen.…”
