Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1663-45-2, is researched, SMILESS is P(CCP(C1=CC=CC=C1)C2=CC=CC=C2)(C3=CC=CC=C3)C4=CC=CC=C4, Molecular C26H24P2Journal, Inorganic Chemistry Communications called Hydrogen storage capacity of novel mixed ligand complexes of lead(II): Molecular structure of [Pb2(tsac)4(μ-dppe)], Author is Al-Jibori, Subhi A.; Amen, Mohamed M.; Alheety, Mustafa A.; Karadag, Ahmet; Wagner, Christoph, the main research direction is lead phosphino aminobenzothiophene acetamidopyrimidine benzimidazolethiol hiosaccharinato complex preparation; crystal structure gas adsorption lead phosphino hiosaccharinato complex.Related Products of 1663-45-2.
[Pb(tsac)2H2O] was used as a synthon for the synthesis of lead(II) thiosaccharinate mixed ligand complexes with the tertiary phosphines; PPh3, Ph2P(CH2)nPPh2, n = 1, dppm; n = 2, dppe; n = 3, dppp or the heterocyclic; 2-aminobenzothiophene (abtH), 2-acetamidopyrimidine (aampH) and 2-benzimidazolethiol (bimsH). The prepared complexes were characterized using; IR, 1H-, 31P-{1H} NMR, molar conductivity, elemental anal. in addition, the crystal structure of [Pb2(tsac)4(μ-dppe)] was resolved by x-ray diffraction anal. of a single crystal. [Pb2(tsac)4(μ-dppe)] crystallizes in the triclinic space group P-1 a 9.0955(5), b 11.4197(6), c 15.3174(7) Å, Z = 2 and refined to R1 = 0.0422. Herein, thiosaccharine shows the ability to coordinate to lead(II) center in a variety of modes, which are monodentate, chelate- bidentate via a nitrogen atom and/ or a sulfur atom of the thiole group. Also, [Pb(tsac)2H2O] and [Pb2(tsac)4(μ-dppe)] were used to examine their ability to store hydrogen. [Pb(tsac)2H2O] and [Pb2(tsac)4(μ-dppe)] are able to store 0.29 and 1.12% H2, resp.
