✦ Synopsis

A 59C0 NMR study of a series of mixed-metal tetrahedral clusters prepared from the basic structures MCo, (M = Fe, Ru) by the substitution of one, two or three carbonyl groups by phosphines, phosphites, thioethers or amines is described. The variations of the chemical shifts and the linewidths are discussed according to the nature of M and the type of ligand. Some theoretical considerations show the difficulty of interpreting rough correlations found between NMR parameters and electronic properties of the ligands.

Wo NMR linewidth measurements are reported which show that hexacyanocobaltate-(III) ion may be used as a sensitive probe of protein interactions with anions in aqueous solutions. Applications are demonstrated to bovine serum albumin where the probe ion binding is monitored as a function of pH and is
