Abstract

Abstract A new metal-organic coordination polymer, [Pb(L)(adip)0.5] (1) was synthesized under hydrothermal conditions by using 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol (HL) and adipic acid (H2adip). The complex 1 was characterized by diffraction and elemental analyses. In complex 1, the binuclear [Pb2L2] units were formed by the OH-deprotonation bridging neighboring Pb(II) atoms, and the adipate linked the binuclear [Pb2L2] units to form a symmetric one-dimensional chain. The 1D chain was further extended to the 2D supramolecular layer structure through π-π interactions between the L ligands.

It is well known that the typical N-donor ligands have witnessed an upsurge in interest due to their free conformation and coordination versatility can give rise to diverse structural motifs (Schöne et al, 2018; Takeuchi et al, 2020; Zhang et al, 2020)
We report a new 2D supramolecular lead coordination polymer [Pb(L)(adip)0.5] (1) with adipic acid (H2adip) and the derivative 1-(1H-imidazo[4,5-f] [1,10]phenanthrolin-2-yl)naphthalen-2-ol ligands

Summary

Introduction

A new metal-organic coordination polymer, [Pb(L)(adip)0.5] (1) was synthesized under hydrothermal conditions by using 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol (HL) and adipic acid (H2adip). The multifunctional organic ligands can be used as linkers to connect the adjacent metal centers for coordination bonding to assemble polymers (Gotthardt et al, 2012; Lan et al, 2019). It is well known that the typical N-donor ligands (such as 1,10-phenanthroline and 2,2-bipyridine) have witnessed an upsurge in interest due to their free conformation and coordination versatility can give rise to diverse structural motifs (Schöne et al, 2018; Takeuchi et al, 2020; Zhang et al, 2020).
