Synthesis and structural characterization of a novel lead dinuclear complex: [Pb(L)(I)(sba)0.5]2

Abstract

A new two-dimensional (2D) metal–organic complex, [Pb(L)(I)(sba)0.5]2 (1, L = 2-(2,4-difluorophenyl)-1H-imidazo[4,5-f][1,10]phenanthroline, H2sba = suberic acid), was synthesized under hydrothermal conditions. The single-crystal X-ray analysis indicates that the asymmetric unit of complex 1 has a distorted [:PbIN2O2] octahedral geometry. It is further extended by two π–π stacking interactions and N–H⋯O hydrogen bonding to form and stabilize 2D supramolecular layer.
