A tetranuclear copper(I) cluster complex with a benzeneselenolate ligand, (Me4N)2[Cu4(SePh)6].CH3OH

Synthesis and characterisation of a hexanuclear copper (I) cluster coordination compound

A novel hexanuclear copper (I) cluster coordination compound has been synthesised by the reaction of N-ethoxy-carbonyl-N'-o-chlorophenylthiourea with cupric chloride in ethanol solution.

Multinuclear Cu(I) Clusters Featuring a New Triply Bridging Coordination Mode of Phosphaamidinate Ligands

Phosphabenzamidine [mes-NH-C(Ph)═P-mes) (1) and phosphaformamidine (mes-NH-CH═P-mes) (4) ligands have been synthesized and characterized. The conjugate bases of 1 and 4 coordinate by each bridging three Cu(I) ions, forming hexa- and tetranuclear clusters Cu₆[mes-N═C(Ph)-P-mes]₃Cl₄Li(THF)₂ (3) and Cu₄[mes-N═CH-P-mes]₄ (5), respectively. Both clusters have been fully characterized using ¹H NMR, ³¹P NMR, and X-ray crystallography. Complexes 3 and 5 exhibit a previously unknown coordination mode of phosphaamidinates, which are far less studied than their well-known amidinate counterparts.

A novel copper-rich open-framework chalcogenide constructed from octahedral Cu4Se6 and icosahedral Cu8Se13 nanoclusters

A unique open-framework chalcogenide was constructed from two kinds of cluster-based secondary building units (SBUs), namely, the icosahedral Cu₈Se₁₃ cluster and the octahedral Cu₄Se₆ cluster.

Copper(i) diselenocarbamate clusters: synthesis, structures and single-source precursors for Cu and Se composite materials

The first Cu(i) compounds supported by dialkyl diselenocarbamates were reported to exhibit tetrahedral, hydride-centered tetracapped tetrahedral and hydride-centered tricapped tetrahedral core structures.
