Metalloligands based on Robson-type amino-thiophenolato macrocycles for assembly of heterotrimetallic complexes.

The ability of macrocyclic Co and Ni aminothiolate complexes to act as metalloligands towards cuprate ions was established. Adduct formation is enabled by a thiolate-to-Cu+ charge transfer (CT) interaction giving stable heterotrimetallics with magnetic properties.
