provides for the synthesis and characterization of the unique Ag(I) pincer complexes [ArNCPh}2(NPh)]Ag+(OTf)− (Ar = 2,5-tBu2C6H3; 2,6-iPr2C6H3). The similar covalent radii of Ag(I) and In(I), prompted a bonding comparison of these species with their In(I) analogues. Coordination of toluene to the Ag center revealed the stronger Lewis acidity of the metal site in these compounds relative to In(I) analogues
双(亚氨基)吡啶骨架可用于合成和表征独特的Ag(I)钳形复合物[ArN CPh} 2(NPh)] Ag +(OTf)-(Ar = 2,5- t Bu 2 C 6 H 3;2,6 - i Pr 2 C 6 H 3)。Ag(I)和In(I)的相似的共价半径促使将这些物质与其In(I)类似物进行键合比较。的协调甲苯相对于In(I)类似物,对Ag中心的分析表明这些化合物中金属位点的路易斯酸性更强。
