 Title    Ligandensubstitution an cw  
 Abstract    Mo(CO)2(PPh3)2(MeCN)(f/2-S02), Kristall-und Molekülstruktur von ci5-Mo(CO)2(PMe3)3(i/2-S02) [1] Ligand Substitution at c/s-Mo(CO)2(PPh3)2(M e C N)(77:-S0 2), Crystal and Molecular Structure of d 5-M o(CO)2(PM e3)3(/72-S0 2) [1] M o (C O)2(PPh3)2(MeCN)(?72-SC)2) reacts with a number of unidentate or tridentate phosphines with displacement of both MeCN and PPh3. Mixtures of up to three different isomers are obtained the structures of which are assigned by IR , 'H, 13C, and 31P N M R , and in one case by X-ray crystallography. The results support earlier observations concerning the relationship between the disposition of donor and acceptor ligands around the metal and the bonding mode of SO ; .
