Nuclear magnetic resonance study of ligand exchange on the hexakis(trimethyl phosphate)scandium(III) ion
Abstract
1 H and 31P N.m.r. studies of scandium(III)–trimethyl phosphate (TMP) solutions show that [Sc(TMP)6]3+[J(45Sc–31P)ca. 35 Hz] is the greatly predominant scandium(III) species in solution, and that its lability towards ligand exchange is intermediate between that of the analogous aluminium(III) and magnesium(II) species.
