摘要：

The synthesis and spectroscopic (NMR, UV-Vis, Mossbauer) characterisation are reported for a series of mercaptoalcohol ligated cluster salts [Q](2)[F4S4(S(CH2)(n) OH)(4)] (Q = NMe4, n = 2, 3, 4, 6; Q = PPh4, n = 2, 3, 4), together with the crystal structures of the three [PPh4](+) salts. The variation of the solid state Mossbauer parameters with ligand alkyl chain length, n, is discussed and related to crystallographic properties. In dimethyl sulfoxide frozen solution, all samples, independent of cation and ligand chain length, n, show the same quadrupole splitting in their Massbauer spectrum. (C) 1999 Elsevier Science S.A.
