Synthesis, Spectral and XRD Studies on Isomeric Chelates of Strontium(II) and Barium(II) with Phthiocol and Plumbagin

Abstract

Metal chelates of strontium(II) and barium(II) with isomeric phthiocol (3-methyl-2-hydroxy-1,4-naphthalene dione) and plumbagin (2-methyl-5-hydroxy-1,4-naphthalene dione) have been synthesized. Molecular structures of these isomeric chelates are investigated with the help of thermogravimetry, infrared and electronic spectroscopy and XRD. The results of structural investigations are employed to explore the nature and consequences of ring isomerism on the physical and structural characteristics of these isomeric chelates.
