Abstract
The dinuclear complex [Cu2L2(µ-OH)(µ-C6H5CO2)][ClO4]2(L = 1,4,7-trimethyl-1,4,7-triazacyclononane) has been synthesized and characterized by X-ray crystallography and from temperature-dependent susceptibility measurements which established a moderately strong, intramolecular, antiferromagnetic exchange coupling (J=–66 cm–1, H=–2JS1·S2, S1=S2=½) and a magneto–structural correlation between the Cu–O–Cu angle and J for complexes containing a CuII 2µ-hydroxo-µ-carboxylato core.Keywords
