The synthesis and spectroscopic characterisation of [ScCl(15-crown-5)(MeCN) ][SbCl6]2, [ScCl2(18-crown-6)][FeCl 4] and [ScCl2([15]aneS2O3)] [FeCl4] ([15]aneS2O3 = 1,4-dithia-7,10,13- trioxacyclopentadecane) are reported, the last containing the first example of thioether-scandium(III) coordination. The structure of [ScCl(15-crown-5)(MeCN)]- [SbCl6]2 reveals a pentagonal bipyramidal cation with axial Cl and MeCN, whilst [ScCl2(18-crown-6)][FeCl 4] is also pentagonal bipyramidal with axial Cl ligands. 1H and 45Sc NMR spectroscopies have been used to study the spcciation in the ScCl3/18-crown-6 system in the presence of the Lewis acids SbCl3 and FeCl3 in anhydrous MeCN. Hydrolysis of any of the above complexes and of [Sc(12-crown-4)2] 3+ (formed from ScCl3(thf)3, crown and SbCl5), results in the formation of [ScCl3(H 2O)3]-crown, the solution NMR spectra of which show a common scandium species and uncomplexed crown ether. The structure of [ScCl 3(H2O)3]·18-crown-6 reveals a mer octahedral scandium species which is hydrogen bonded via the scandium-coordinated water to the 18-crown-6 (secondary coordination) leading to infinite chains. Similar complexes have been isolated directly from reaction of ScCl3·6H2O and the crown ethers in absolute ethanol, including [ScCl3(H2O)3] n·(crown) (H = 1 or 2, crown = 18-crown-6; n= 2, crown = 15-crown-5 or 12-crown-4). Hydrated scandium nitrate and the crown ethers react in ethanol solution to form a surprisingly diverse range of structural types containing the crown ethers hydrogen bonded to the scandium-aquo-nitrato or scandium-aquo-hydroxo-nitrato complexes. X-Ray crystal structures are reported for [Sc(H2O)2(NO3)3]·(12- crown-4)2, [Sc(H2O)4(NO3) 2]NO3·15-crown-5 and [Sc2(NO 3)2(H2O)6(OH)2](NO 3)2·12-crown-4. However, in the related [Sc 2(NO3)4(H2O)4(OH) 2[Na(12-crown-4)2](NO3HH2O) 3 the hydrogen bonding occurs between the lattice water and the scandium dimer unit. The Royal Society of Chemistry 2003.
