Hydrothermal syntheses, characterizations, and luminescence of three new complexes based on 4,6-dibenzoylisophthalic acid

Abstract

Three new complexes with embellished dicarboxylate, [(2,2′-bpy)₂(H₂O)₂] (1), [(2,2′-bpy)₂(H₂O)₂] (2), and [Ni^IIL(4,4′-bpy)(H₂O)] (3) (H₂L = 4,6-dibenzoylisophthalic acid, 2,2′-bpy = 2,2′-bipyridine, 4,4′-bpy = 4,4′-bipyridine), were synthesized under hydrothermal conditions and characterized by elemental analysis, IR spectra and X-ray diffraction. Complexes 1 and 2 are binuclear structures with 16-membered rings. Complex 3 shows a 2-D sheet structure. Intermolecular O–H ··· O interactions extend 1 and 2 into 1-D chains. Luminescence properties have been investigated for 1 and 2.
