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, 1 (R = H) and 2 (R = H), and their related single ring derivatives, 3 (R = H) and 4 (R = CH2C6H5), with copper(I) is reported. Solid 3:1 (metal:ligand) complexes of type [Cu3L](PF6)3 (L = 1 and 2, R = H) and single ring derivatives of type [CuL]PF6 (L = 3, R = H; L = 4, R = CH2C6H5) were isolated; the X-ray structure of [CuL]PF6 (L = 3, R = H) showed that the four macrocyclic donor atoms coordinate to the copper(I) in a quasi-tetrahedral manner (Cu–N 2.089, 2.096(4); Cu–S 2.239, 2.264(2) Å, X–Cu–Y 104.5(1)–115.4(1))°.
