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: 89972-77-0, is researched, SMILESS is CC1=CC=C(C2=CC(C3=NC=CC=C3)=NC(C4=NC=CC=C4)=C2)C=C1, Molecular C22H17N3Journal, Journal of Coordination Chemistry called Synthesis, spectroscopy, thermal behavior, and X-ray crystal structure of two lead(II) complexes with 4′-(4-tolyl)-2,2′;6′,2”-terpyridine (ttpy), Author is Saghatforoush, Lotfali; Adil, Karim; Sahin, Ertan; Babaei, Somayyeh; Musevi, Seyid Javad, the main research direction is preparation acetate bridged dimeric lead tolylterpyridine complex; crystal structure acetate bridged dimeric lead tolylterpyridine complex; cyclic voltammetry acetate bridged dimeric lead tolylterpyridine complex.COA of Formula: C22H17N3.
Two new dimeric Pb(II) complexes with 4′-(4-tolyl)-2,2′;6′,2”-terpyridine (ttpy), [Pb(ttpy)(μ-AcO)]2(PF6)2 (1) and [Pb(ttpy)(μ-AcO)I]2 (2), were synthesized and characterized by CHN elemental anal., 1H NMR, 13C NMR, IR spectroscopy, and structurally analyzed by x-ray single-crystal diffraction. The thermal stability of these compounds was studied by TGA and DTA. Single crystal x-ray anal. shows that 1 and 2 are dimeric units with Pb-(μ-AcO)2-Pb-type bridging, and the coordination number in 1 is six and in 2 is seven. The arrangement of donors suggests a gap in the coordination geometry around lead, possibly occupied by stereo-active lone pair of electrons on Pb(II), so the coordination sphere is hemidirected. Also, dimeric units are connected by a network of hydrogen bonds and π-π stacking as well. Electrochem. properties of free ligand and complexes were studied in the presence of tetra-Bu ammonium perchlorate as supporting electrolyte and by using a glassy carbon electrode. Both lead complexes show irreversible Pb(II) oxidation Cyclic voltammetry indicates that these processes are diffusion-controlled. The data from electrochem. studies show that the total limiting current of each of the studied complexes corresponds to two-electron transfer.
