Gold(I) Phosphine Complexes Containing Selenocarbamate Esters: Crystal and Molecular Structure of N-phenyl-O-methylselenocarbamate

Abstract

A series of both mono- and dinuclear gold(I) phosphine complexes containing deprotonated N-phenyl-O-methylselenocarbamate of the type [AuSeC(OMe) = NPh(P)] and [Au ₂ SeC(OMe) = NPh ₂ (PP)] (P = PPh ₃ , P(o-tolyl) ₃ , PTA; PP = dppm, dppe, dppp, dppf) were prepared and characterized by spectroscopic techniques. The X-ray crystal structure of SeC(OMe)═N(H)Ph is also reported and shows the molecule to exist in the E-conformation. Centrosymmetrically related dimers associate in the crystal structure by N─H…Se interactions.
