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, Journal of Molecular Structure called Novel Hg(II) and Pd(II) benzotriazole (Hbta) complexes: Synthesis, characterization, X-ray crystal structure of [Pd(PPh3)(μ-bta)Cl]2. DMSO and thermodynamic study of their H2 storage, Author is Al-Jibori, Subhi A.; Al-Doori, Luma A.; Al-Janabi, Ahmed S. M.; Alheety, Mustafa A.; Akbas, Huseyin; Karadag, Ahmet, which mentions a compound: 1663-45-2, SMILESS is P(CCP(C1=CC=CC=C1)C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4, Molecular C26H24P2, Reference of 1,2-Bis(diphenylphosphino)ethane.
Benzotriazole (Hbta) complexes with Hg(II) and Pd(II) of the types: [Hg(bta)2] (1), [Hg(bta)2(diphos)]; diphos = dppe (2), dppp (3) or dppb (4), [Hg(bta)2(PPh3)2] (5), [Pd(Hbta)2Cl2] (6), [Pd(bta)Cl]2(7) and [PdCl(bta)(PPh3)]2. DMSO (8) were prepared and characterized by elemental analyses, conductivity measurements, IR, 1H- and 31P-{1H} NMR spectra.[Pd(PPh3)(μ-bta)Cl]2. DMSO (8) was structurally characterized by single-crystal x-ray diffraction. Structural information exposed that benzotriazole acts as a bidentate bridging ligand bonded through the deprotonated nitrogen and the neutral nitrogen atoms. The hydrogen storage ability of complexes (1-4) was studied after detecting their BET surface area. 1 Is able to store 3.35% phys. at 77 K under 120 bar.
When you point to this article, it is believed that you are also very interested in this compound(1663-45-2)Reference of 1,2-Bis(diphenylphosphino)ethane and due to space limitations, I can only present the most important information.
