“…The Cu–Cu bond distances in 7 are similar to those observed in 5 . It is worth noting that while several dithiocarbamate clusters of Cu(I) − ,− and Ag(I) − are known, none are from CS 2 insertion or derived from a dinuclear species.…”

Dinuclear Cu(I) and Ag(I) complexes, Cu2[(2,6-Me2C6H3N)2C(H)]2, 1, Ag2[(2,6-Me2C6H3N)2C(H)]2, 2, Cu2[2,6-(i)Pr2C6H3N)2C(H)]2, 3, and Ag2[(2,6-(i)Pr2C6H3N)2C(H)]2, 4, were synthesized from reactions of [Cu(NCCH3)4][PF6] with Na[(2,6-R2C6H3N)2C(H)] and AgO2CCH3 with [Et3NH][(2,6-R2C6H3N2C(H)], R = Me, (i)Pr. Carbon disulfide was observed to insert into the metal-nitrogen bonds of 1 to produce Cu4[CS2(2,6-Me2C6H3NC(H)═NC6H3Me2)]4, 5, with a Cu4S8 core, which represents a rare transformation of dinuclear to tetranuclear species. Insertion is also observed with 2 and CS2, with the product likely being polymeric, 6. With the (i)Pr-derivatives, CS2 insertion was also observed, albeit at much slower rate, with 3 and 4 producing hexanuclear clusters, M6[CS2(2,6-Me2C6H3NC(H)═NC6H3Me2)]6, M = Cu, 7; Ag, 8. Complexes 1 and 5 display green luminescence, a feature not shared by their Ag(I) analogs nor with 3. Notably, oxygen acts as a collisional quencher of the luminescence from 1 and 5 at a rate faster than most metal-based quenchometric O2 sensors. For example, we find that complex 1 can be rapidly and reversibly quenched by oxygen, presenting a nearly 6-fold drop in intensity upon switching from nitrogen to an aerated atmosphere. The results here provide a platform from which further group 11 amidinate reactivity can be explored.

“…There is now a fair amount of single-crystal X-ray diffraction data on a series of CuXL complexes, sufficient to stage a comprehensive discussion of steric and electronic factors that determine the solid-state structure of these compounds (X = Cl, Br, I). The results of the structural studies are summarized in Table 3 (6 ).…”

A senior undergraduate project in inorganic chemistry is described, involving the reaction of copper(II) bromide and the potential bidentate sulfur ligand bis(N,N-dimethylthiocarbamoyl) sulfide (N,N,N',N'-tetramethylthiuram monosulfide). The students are required to interpret the unusual pattern of reactivity observed, and to characterize the products generated, bromo-bis(N,N-dimethylthiocarbamoyl)sulfidocopper(I) and 2,5-bis(N,N-dimethyliminium)-1,3,4-trithiolane tribromocuprate(I), by means of elementary analyses, infrared spectroscopy, and magnetic susceptibility measurements. Additional topics for discussion are suggested. The behavior of the reactants in this system would not normally be evident to students at an undergraduate level, but would be accessible after rigorous interpretation of the experimental evidence.

“…The molecular geometry and structural parameters observed were comparable to those reported here. Thermal motion and an insufficient number of data led to an unsatisfactory structure solution 15. Repeated attempts to reproduce this synthetic result were unsuccessful.…”

Crystal and Molecular Structures of a Neutral Pentanuclear Copper(I)−Iodide Complex

Abstract: The novel pentanuclear species ( 1 ) is prepared from copper(I) iodide and tetraethylthiuram monosulfide. It features a central Cu3I3 cage with two fused CuLI units. This structure is one of the scarce examples of copper(I) pentanuclear compounds so far reported.
