Abstract

Abstract Two lead(ii) coordination complexes with 2-(4-fluoro-phenyl)-1H-imidazo[4,5-f][1,10]phenanthroline formulated as [Pb(L)2(tlba)2)] (1) and [Pb(L)(dpea)]2 (2) (HTLBA = 2,3,4,5-tetrachlorobenzoic acid, H2dpea = diphenic acid) were synthesized under hydrothermal conditions. In 1, the neighboring [Pb(L)2(tlba)2)] molecules formed into a two-dimensional (2D) layer structure with C–Cl⋯π interactions and N–H⋯O hydrogen bond interactions. For 2, Pb1 and Pb1i ions are connected by four carboxylate groups from two dpea anions to yield a binuclear unit. Two L ligands are situated in two flanks of the dimer. The L ligands from dimers in the vicinity pile up by two π–π interactions to form a 2D supramolecular structure. Moreover, PXRD of 2 was also studied.

含菲罗啉衍生物的两种新型铅(ii)配合物:合成和表征
摘要在水热条件下合成了2-(4-氟-苯基)-1H-咪唑并[4,5-f][1,10]菲咯啉的铅(Ⅱ)配位配合物[Pb(L)2(tlba)2)](1)和[Pb(L)(dpea)]2(2)(HTLBA=2,3,4,5-四氯苯甲酸,H2dpea=二苯酸)。在1中,相邻的[Pb(L)2(tlba)2)]分子形成二维(2D)层结构,具有C–Cl·π相互作用和N–H·O氢键相互作用。对于2,Pb1和Pb1i离子由两个dpea阴离子的四个羧酸根连接,产生双核单元。两个L配体位于二聚体的两侧。附近二聚体的L配体通过两个π–π相互作用堆积起来,形成2D超分子结构。此外,还对2的PXRD进行了研究。
