These three Cu 2x Se x (x ¼ 70; 73) clusters can thus be described as consisting
of 2.6 Â 2.6 Â 0.9 nm
3 sections of a bulk lattice. Cementing this analogy is a recent
report describing the recovery of the cluster [Cu 70 Se 35 (PEt 3 ) 21 ] 9 from the evaporation of cubic Cu 2 Se and its co-condensation with PEt 3 [37]. This report of
Fig. 13.6. Two projections of the cluster [Cu 146 Se 73 (PPh 3 ) 30 ] 8
illustrating the layered nature of the selenium framework (top)
and the overall triangular shape (bottom) of the cluster (carbon
atoms not illustrated) [31].
