Dinucleating Naphthyridine-Based Ligand for Assembly of Bridged Dicopper(I) Centers: Three-Center Two-Electron Bonding Involving an Acetonitrile Donor

Dinucleating Naphthyridine-Based Ligand for Assembly of Bridged Dicopper(I) Centers: Three-Center Two-Electron Bonding Involving an Acetonitrile Donor:

Unusual bonding: A ligand system that promotes formation of a rare μ-η¹:η¹ acetonitrile-bridged dicopper(I) complex (see picture) has been developed. The acetonitrile ligand is involved in a three-center two-electron bond supported by a cuprophilic interaction. The labile acetonitrile ligand can be substituted with xylyl isocyanide or CO.

From Letko's present work-group. Highly relevant to his thesis work.
