Synthesis And Structural Characterization Of A Novel 2d Supramolecular Lead Coordination Polymer With Phenanthroline Derivate And Adipic Acid

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 (H(2)adip). 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 pi-pi interactions between the L ligands.
