Abstract From the reactions of (THF)M(CO)5 (M = Cr, W) with 4-phenyl-1,2,3-thiadiazol, 4-methyl-5-carboxylic acid-1,2,3-thiadiazol, 4-methyl-5-carboxylic acid ethyl ester-1,2,3-thiadiazol and 4-methyl-1,2,3-selenadiazol, pentacarbonyl-complexes are obtained as air stable compounds. IR spectra of products of similar reactions with M = Mo provide some evidence of the formation of analogous complexes. The thiadiazol complexes are also accessible directly, by photochemical displacement of carbonmonoxid in THF from the parent carbonyl. The X-ray structures of pentacarbonyl-(4-phenyl-1,2,3-thiadiazol)-tungsten and pentacarbonyl-(4-methyl-1,2,3-selenadiazol)-chromium show the coordina-tion of the ligand to the pentacarbonyl-metal-fragment via the nitrogen in position 2.
