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 Copper(II) is harder than copper(I): a novel mixed-valence example from alkoxide chemistry, published in 2003-03-31, which mentions a compound: 75732-01-3, Name is Mesitylcopper(I), Molecular C9H11Cu, SDS of cas: 75732-01-3.
Partial oxidation or disproportionation of tetrameric 2-allyl-6-methylphenoxocopper(I) leads to the formation of a novel trinuclear mixed-valence Cu(I)/Cu(II) alkoxide [Cu3[μ-η2-OC6H3-6-Me-2-(CH2CH:CH2)-κO]4], in which the central copper(II) atom is coordinated in a distorted square-planar configuration by four μ-oxide ligands, whereas the peripheral copper(I) centers are each bonded to two C:C groups and two μ-oxide ligands in a tetrahedral arrangement.
From this literature《Copper(II) is harder than copper(I): a novel mixed-valence example from alkoxide chemistry》,we know some information about this compound(75732-01-3)SDS of cas: 75732-01-3, but this is not all information, there are many literatures related to this compound(75732-01-3).
