Synthesis and crystal structure of a new 2D supramolecular Cd(II) complex with 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone ligand

Abstract

A new Cd(II) complex, [Cd(PMBP)2(CH3OH)2] (PMBP = 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone), has been synthesized and characterized by elemental analysis, IR spectroscopy, thermal gravimetric analysis, fluorescence analysis, and X-ray single-crystal diffraction. In the complex, a slightly distorted octahedral geometry of cadmium ion is coordinated by six oxygen atoms, and the cadmium ion locates in the center position. The complex is a monomeric species, which is extended into 2D supramolecular architecture by strong intermolecular hydrogen bonds. Moreover, the intramolecular hydrogen bonds and C-H···π interactions are also found in the complex so that the 2D supramolecular network is consolidated.
