✦ Synopsis

The reactions of titanium(III) and (IV) chlorides with the crown thioether [93aneS3 were investigated. [TiCt 3-(MeCN)3 ] gives a purple 1:1 adduet with a proposed octahedral structure involving tridentate foe-attachment of the ligand. With [TiClg(MeCN)2] the identity of the yellow 1:1 adduct obtained is discussed in terms of a six-coordinate species with bidentate ligand chelation. The title compound was isolated from the reactions of [9laneS 3 with [TiC13(MeCN) 3] [SbC16] (by accident) and iron filings/SbCl5 in MeCN solution and characterised crystallographically. The cation has two macrocyclic ligands coordinated facially to a six-coordinate Fe z § ion; the anion comprises dimeric [(SbC14)2] units linked together into a polymeric chain by weak halogen bridging.
