Catena-Poly[[(2,9-dimethyl-1,10-phenanthroline-κ2 N,N′)lead(II)]-di-μ-2-hydroxybenzoato-κ3 O 1,O 1′:O 2;κ3 O 2:O 1,O 1′

Abstract

In the title polymeric comound, [Pb(C7H5O3)2(C14H12N2)] n , the PbII atom is located on a twofold rotation axis and is coordinated by two N atoms from one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and six O atoms from four 2-hydroxybenzoate anions. The compound forms a zigzag polymeric chain along the c axis through bridging hydroxy groups of two 2-hydroxybenzoate ligands. The crystal packing is stabilized by the intramolecular hydrogen bonding and π–π interactions between dmphen rings of neighboring molecules, with a distance between the ring planes of 3.385 (3) Å.
