High-nuclearity Cu hydride nanoclusters of Cu 22 H 19 and Cu 20 H 13 consolidated by an N-containing triphosphine ligand: synthesis, characterization and catalysis

Two Cu hydride nanoclusters, [Cu 22 H 19 ] and [Cu 20 H 13 ], are synthesized and their compositions and structures are determined by 1 H NMR, high-resolution ESI-MS and single-crystal X-ray diffraction analysis.
