"Reaction of the incomplete cuboidal cationic cluster [W3S4H3-(dmpe)(3)](+) (dmpe = 1,2-bis(dimethylphosphino)ethane) with Cu-1 compounds produces rare examples of cationic heterodimetallic hydrido clusters of formula [W3CuClS4H3(dmpe)(3)](+) ([1](+)) and [W3Cu(CH3CN)S4H3(dmpe)(3)](2+) ([2](2+)). An unexpected conversion of [1](+) into [2](2+), which involves substitution of chloride by CH3CN at the copper centre, has been observed in CH3CN/H2O mixtures," investigators in Spain report.
"Surprisingly, formation of the acetonitrile complex does not occur in neat acetonitrile and requires the presence of water. The kinetics of this reaction has been studied and the ...
