Linked macrocyclic systems. Interaction of copper(I) with tris-ring N2S2-donor macrocycles and their single-ring analogues

The interaction of two tri-linked N2S2-donor macrocyclic ligands and two single-ring analogues with Cu(I) is reported. Corresponding complexes of type [Cu3L](PF6)3 and single ring derivatives of type [CuL]PF6 have been synthesised. The X-ray structure of one single ring derivative showed that the four macrocyclic donor atoms coordinate to the Cu(I) in a quasi-tetrahedral manner; similar metal coordination geometries are proposed for the remaining three complexes.
