资源简介:
The reaction of silver acetate with a phosphinothiosemicarbazone ligand, HLPPh, yielded the tetranuclear silver compound [Ag4(LPPh)4]·2MeOH (1), which after recrystallization results in the cocrystallization of two different silver clusters, [Ag4(LPPh)4]a[Ag4(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.
