摘要：

The chalcogenoimidazoline complexes NR-CMe-CMe-NR-C=X . M(CO)(5) (VIII-XI; R = Me, iso-Pr; X = S, Se, Te; M = Cr, Mo, W) are obtained from the metal hexacarbonyls (M = Cr, Mo, W) and the chalcogenoimidazolines IV-VIL. ln these complexes the chalcogeno ligands exhibit strong donor properties according to the sequence Te > Se > S which is demonstrated by n. m. r. and i. r. data. The X-ray structures of N(iso-Pr)-CMe-CMe-N(iso-Pr)-C=X . Cr(CO)(5)(X = S; Se; VIIIa, IXa) are reported.
