Gold(I) phosphine complexes containing selenocarbamate esters:: Crystal and molecular structure of N-phenyl-O-methylselenocarbamate

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 [Au2SeC(OMe)= NPh2(PP)] (P = PPh3, 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 NH center dot center dot center dot Se interactions.
