Stable thiolate adducts of Rh2(OAc)4 - assembly of hexametallic Ni4Rh2 complexes.

Thiolate adducts of dirhodium(II) tetraacetate have proven difficult to prepare. We isolated a stable, paramagnetic Ni4Rh2 adduct containing Ni-based metallothiolates bound in axial positions of the Rh24+ core. The adduct formation is accompanied by a change of the magnetic exchange interaction in the dinuclear Ni2 subunits.

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.
