Ligand-Controlled Syntheses of Copper(I) Complexes with Metal-Metal Interactions: Crystal Structure and Relativistic Density Functional Theory Investigation

A family of di-, tri-, and tetranuclear copper(I) complexes supported by length-controlled silaamidinate ligands have been synthesized to show short Cu-I-Cu-I distances (2.43-2.62 angstrom) and feature a linear or bent metal-metal arrangement, which is elucidated by a relativistic density functional theory calculation.
