摘要
合成了氮烃基化三角架tren配体L·3HCl(L= [N, N′, N″ 三(4 甲氧苄基) 三(2 氨乙基)胺] ),并得到了其单核Ag(I)配合物 [AgL]NO3.晶体结构研究表明Ag(I)离子被三角架配体L四齿螯合,与罕见的笼形结构相似,NOˉ根没有参加配位,而作为氢键的受体将分子组装成二维超分子结构.
N-alkylated tripodal tren ligand L·3HCl (L_( )=\[N, N^(′), N^(″)-tris(4-methoxylbenzyl) tris((2-aminoethyl)amine)\] or (4-methoxybz)_3tren) and its mononuclear Ag(I) complex \NO_(3 )(1) were synthesized. Crystal structure analysis of 1 indicates that the Ag(I) center is tetradentately chelated by the tripodal ligand L, a structure very similar to those rarely observed cage-like ones. The uncoordinated NO^-_(3 )groups, acting as acceptor of hydrogen bonding, assemble the molecule into 2D supramolecular structure.
