    • Abstract

       

      Prof. Priyadaranjan Ray’s contribution to inorganic chemistry and related disciplines is enormous. His work on the elucidation of valency and structure of coordination compounds through magnetic measurements, proposition of Ray–Dutt twist mechanism and the discovery of inner metallic complexes of higher than second-order made him internationally famous. He first reported the two ligand isomers of thiosulphate ion and designed several organic reagents for the detection and estimation of metal ions. Stabilization of unusual oxidation state of metal ions through coordination with suitable ligand was also his important work. Besides science, he was interested in its history. Scientific activities as well as a brief life-sketch of this Indian stalwart of science is summarized in this present endeavour.
