摘要 : The 4-aryl substituted pyrazolate ligands, L1(Ph)H and L1(Naph)H, were synthesized by Suzuki-Miyaura cross-coupling and combined with metal sources to give cyclic trinuclear structures [AgL1(Ph)](3), [AuL1(Ph)](3), [AgL1(Naph)](3)... 展开 The 4-aryl substituted pyrazolate ligands, L1(Ph)H and L1(Naph)H, were synthesized by Suzuki-Miyaura cross-coupling and combined with metal sources to give cyclic trinuclear structures [AgL1(Ph)](3), [AuL1(Ph)](3), [AgL1(Naph)](3), and [AuL1(Naph)](3). The aryl group determined the crystal packing of these cyclic trinuclear complexes with the phenyl systems exhibiting stair type solid state structures and the naphthyl complexes exhibiting irregular structures with spaces occupied with some solvent molecules. These differences in solid-state structures were accompanied by differences in M-N stretching frequencies and temperature dependent photoluminescence. 收起
