The reaction of the cyclo oligomers R n Sb n S n [ n  = 2, 3; R = CH(SiMe 3 ) 2 ] with W(CO) 5 thf (thf = tetrahydrofuran) in thf results in trapping of the dimer in cyclo ‐[R 2 Sb 2 S 2 ][W(CO) 5 ] 2 ( 1 ). An X‐ray crystal structure analysis revealed that the complex contains a four‐membered antimony–sulfur ring in an almost planar conformation, where the alkyl groups occupy cis positions and the W(CO) 5 units are bonded trans to the alkyl groups on the antimony atoms.
