Factors involved in the nuclearity of silver thiosemicarbazone clusters: cocrystallization of two different sized tetranuclear silver(I) clusters derived from a phosphinothiosemicarbazone ligand.
The reaction of silver acetate with a phosphinothiosemicarbazone ligand, HLPPh, yielded the tetranuclear silver compound [Ag 4(LPPh) 4].2MeOH ( 1), which after recrystallization results in the cocrystallization of two different silver clusters, [Ag 4(LPPh) 4] (a)[Ag 4(LPPh) 4] (b).8MeOH ( 2). The factors involved in the assembly of tetranuclear compounds derived from thiosemicarbazone ligands and the structural differences between the two clusters are analyzed herein. Additionally, HLPPh and complex 1 exhibit photoluminescence in solution at room temperature.
