The reaction of [PPh4](2)[WS4] in CH3CN with excess n-propylbromide or n-butylbromide gave alkylthiolatotrithiotungstate complexes, [PPh4][WS3(SR)] (1: R = n-propyl; 2: R = n-butyl). The analogous reaction with 1-bromomethyl-4-chloromethyl-benzene afforded a benzylthiolatotrithiotungstate complex, [PPh4][WS3(SCH2C6 H4CH2Cl-4)] (3), whereas the reaction with 1,4-bis-bromomethyl-benzene led to isolation of a dinuclear complex [PPh4](2)[WS3(mu-SCH2C6H4CH2S)WS3] (4). Complexes 1-4 were characterized spectroscopically and the crystal structures of 1/2 center dot(1)/2C6H6 and 3 have been determined by X-ray diffraction.
