Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Dalton Transactions called Why are the {Cu4N4} rings in copper(I) phosphinimide clusters [Cu{μ-N:PR3}]4 (R = NMe3 or Ph) planar?, Author is Robinson, Thomas P.; Price, Richard D.; Davidson, Matthew G.; Fox, Mark A.; Johnson, Andrew L., which mentions a compound: 75732-01-3, SMILESS is [Cu]C1=C(C)C=C(C)C=C1C, Molecular C9H11Cu, Safety of Mesitylcopper(I).

The Cu phosphinimide complexes [Cu{μ-N:PR3}]4 (1, R = NMe2 and 2, R = Ph) were obtained in good yields from the reactions of Cu[Mes] (Mes = mesityl, C6H2Me3-2,4,6) with the corresponding iminophosphoranes, HNPR3. The mol. structures of 1 and 2 reveal planar eight-membered {Cu4N4} rings which contrasts with the saddle-shaped {M4N4} rings found in related metal phosphinimide complexes. According to computations, there is negligible aromaticity in the planar {Cu4N4} rings in 1 and 2 and the saddle shape observed in related {M4N4} rings is due to steric factors.

Keywords: crystal structure copper phenoxide phosphine complex; structure copper phenoxide phosphine dinuclear tetranuclear; copper phenolate phosphine complex preparation structure; phenoxide copper phosphine complex preparation structure.They researched the compound: Mesitylcopper(I)( cas:75732-01-3 ).Reference of Mesitylcopper(I). Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:75732-01-3) here.

Two phenolatocopper(I) derivatives, [Cu4(PPh3)4(OPh)4] (1) and [Cu2(PPh3)3(OPh)2] (2), were prepared by the addition of triphenylphosphine to copper(I) phenoxide, obtained from mesitylcopper(I) and phenol. Characterization by crystal structure determination showed 1 to be a tetramer with a cubane-type Cu4O4 core in which Cu-O distances range from 2.05(2)-2.26(2) Å. 2 Is a μ2-phenoxide dimer in which one copper(I) center is four-coordinated by two phenoxide and two triphenylphosphine ligands, while the other is coordinated by a single triphenylphosphine ligand and thus three-coordinated. Complex 1 crystallizes as the solvate [Cu4(PPh3)4(OPh)4]·(PhMe)2 in the monoclinic space group P21/c with a 14.822(7), b 23.160(4), c 28.193(6) Å, β 98.64(2)° at -90° and Z = 4; full-matrix least-squares refinement yielded R = 0.082 for 529 parameters and 3931 observed reflections.

Name: Mesitylcopper(I). The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Mesitylcopper(I), is researched, Molecular C9H11Cu, CAS is 75732-01-3, about Dimeric Copper and Lithium Thiolates: Comparison of Copper Thiolates with Their Lithium Congeners. Author is Zou, Wenxing; Zhu, Qihao; Fettinger, James C.; Power, Philip P..

The direct reactions of the large terphenyl thiols HSAriPr4 (AriPr4 = -C6H3-2,6-(C6H3-2,6-iPr2)2) and HSAriPr6 (AriPr6 = -C6H3-2,6-(C6H2-2,4,6-iPr3)2) with stoichiometric amounts of mesitylcopper(I) in THF at ca. 80°C afforded the first well-characterized dimeric copper thiolato species {CuSAriPr4}2 (1) and {CuSAriPr6}2 (2) with elimination of mesitylene. The complexes 1 and 2 were characterized by NMR and electronic spectroscopy as well as by X-ray crystallog. They have dimeric Cu2S2 core structures in which the two copper atoms are bridged by the sulfurs from the thiolato ligands and feature short Cu…Cu distances near 2.4 Å as well as a weak copper-flanking aryl ring interaction from a terphenyl substituent. The structures of the planar Cu2S2 cores bear a resemblance to the Cu-A site in nitrous oxide reductase in which two cysteines also bridge two copper atoms. The related dimeric Li2S2 structural motif was also observed in the lithium congeners {LiSAriPr4}2 (3) and {LiSAriPr6}2 (4) which were synthesized directly from the thiols and n-BuLi in hexanes. However, despite the very similar effective ionic radii of the Li+ (0.59 Å) and Cu+ (0.60 Å) ions, the Li…Li structures display very much longer (by more than ca. 0.5 Å) separations than the corresponding Cu…Cu distances in 1 and 2, which may be due to weaker dispersion interactions.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Lewis Base Adducts of Barium/Copper tert-Butoxides: Synthesis and Thermolysis of [BaCu2(OtBu)4]n and [L2Ba2Cu4(OtBu)8] (L = Me3NO and Et3PO).

Reaction of copper(I) mesityl with [Ba(OtBu)2(t-BuOH)2]4 yields insoluble [BaCu2(OtBu)4]n, which dissolves by adduct formation (L = Me3NO or Et3PO) to form soluble L2Ba2Cu4(OtBu)8. For L = Me3NO, this mol. is shown by x-ray diffraction to have a structure based on a trans-Ba2Cu4 octahedron, with all Ba/Cu edges bridged by μ2-OtBu units; one L binds to each Ba (monoclinic, space group P21/c, R = 0.0822). Bulk thermolysis, TGA, and product anal. revealed that OtBu units undergo not only O/C cleavage but also C/C cleavage, the latter to form carbonate and nonvolatile hydrocarbon products, in addition to BaO and CuO. The intended oxidant Me3NO shows no great tendency to oxidize Cu(I).
