The Syntheses and Structures of Two New Zn(II) Complexes Based on 3-Nitrobenzoato Ligand
Abstract:
Two new Zn (II) coordination polymers with 3-nitrobenzoato ligands have been prepared, and their structures have been characterized by single-crystal X-ray diffraction techniques. The structure of [Zn (3-nbz)2(μ-4,4'-bpy)]n (1) (3-nbz = 3-nitrobenzoato, 4,4'-bpy = 4,4'-bipyridine) shows 1-D chains originating from terminal 3-nbz ligands and μ-4,4'-bpy molecules. The chains are further connected through face-to-face π stacking interactions to genenate a 2-D supramolecular layer. In Zn (3-nbz)2(2,2'-bpy) (2) (2,2'-bpy = 2,2'-bipyridine), carboxylate groups exhibit chelated bidentate to give discrete mononuclear units, which are linked by face-to-face π-π and C-H···π interactions to produce a 1-D supramolecular chain.
