Synthesis, Structural Characterization and Crystal Structure of Selenium Bearing 3-(Phenylseleno) Propylammonium Acetate Salt and its Cleavage on Reaction with Mercury(II) and Tin(IV) Salts

摘要

Abstract 3-(Phenylseleno) propylammonium acetate, C₉H₁₄NSe+ C₂H₃O₂ –, L 1 , the first example of a selenium bearing acetate salt has been synthesized and characterized by spectroscopic, NMR, DSC and single crystal X-ray crystallographic techniques. L 1 crystallizes with one cation–anion pair in the asymmetric unit. Reactions of L 1 with four different metal salts revealed four new selenium bearing compounds (1–4) whose identities are characterized by spectroscopic and NMR techniques. The crystal structure of Compound 1, [C₉H₁₄NSe]₂+ [ClO₄]₂–, whose crystal structure has been confirmed. It crystallizes with two independent cation–anion pairs in the asymmetric unit. Both L 1 and Compound 1 display strong N–H···O hydrogen bond intermolecular interactions which help stabilize crystal packing in the unit cell.
