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 Heterometallic Fluoroalkoxides of Barium and Copper(I). Syntheses and Structures of [(Me3NO)2Ba2Cu4(TFTB)8] and [(THF)2Ba2Cu2(HFTB)6], published in 1997-10-22, which mentions a compound: 75732-01-3, Name is Mesitylcopper(I), Molecular C9H11Cu, HPLC of Formula: 75732-01-3.
Reaction of HORF and in situ synthesized [Ba(ORF)2] (from Ba[N(SiMe3)2]2(THF)2 and HORF) with CuMes yields, in THF, [(THF)2Ba2Cu2(OCMe(CF3)2)6] (1). In the case of HORF = HOCMe2CF3, only upon addition of Me3NO is a soluble product obtained: [(Me3NO)2Ba2Cu4(OCMe2CF3)8] (2). 1 And 2 were characterized by x-ray crystallog. (1: triclinic, space group P1̅, R = 0.0557; 2: monoclinic, space group C2/c, R = 0.0643). 1 Has a square-planar Ba2Cu2O4 core structure with two addnl. alkoxides bridging the two bariums, giving the barium a tbp coordination environment. The structure of 2 is markedly different in that it has one more Cu-(OR) unit inserted into the Ba-(OR)-Ba unit. This gives the Ba2Cu4 core structure the shape of an octahedron and barium a square-pyramidal coordination environment. These structures are compared and contrasted with the structures of [Ba2Cu4(OCEt3)8], [(Et3PO)2Ba2Cu4(OtBu)8], and [(Me3NO)2Ba2Cu4(OtBu)8].
Although many compounds look similar to this compound(75732-01-3)HPLC of Formula: 75732-01-3, numerous studies have shown that this compound(SMILES:[Cu]C1=C(C)C=C(C)C=C1C), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
