Structures of Polymetallaorganosiloxanolates—a Novel Class of Organosilicon Metal Complexes
Journal of Organometallic Chemistry
Single crystal X-ray diffraction studies have revealed the nature and structure of eight types (I–VIII) of polymetallaorganosiloxanolates, representatives of a novel class of the organosilicon metal complexes. Most of the complexes (types I–VII) have sandwich structures with a layer of metal cations between two macrocyclic siloxanolate ligands. In type VIII a single such ligand envelops four inner Cu2+ ions to form a globular species.
