The structural arrangement for the DDP (dialkyldithiophosphate) ligands is different from that of Cu 6(DDP) 6, but is the same as that of Ag 6 [SSP(O i Pr) 2] 6.展开更多

The clusters are packed on each other through strong n-n interactions to form ^1D ＇brick＇ chains, between which the solvated benzene molecules are located. TG analysis showed that cluster 1 could completely liberate the vip benzene molecules at 105℃ and the coordinated benzene molecules at 180 ℃. In solid state, cluster 1 exhibits fluorescence, and the emission band is red-shifted compared with that of free ligand bdb.展开更多
