Three bimetallic organic-inorganic hybrids based on the [V2O6]2- building unit, [Cu(pty)(V2O6)]·H2O (1), [Cu(pty)(V2O6)] (2), [Cu(tpy)(V2O6)] (3), (pty = 4′-(4”-pyridyl)-2,2′:6′,2”-terpyridine, tpy = 2,2′:6′,2”-terpyridine), were synthesized via a one-pot method. Hybrid 1 has a 1D straight chain architecture with [V2O6]2- clusters and Cu-pty complexes; hybrids 2 and 3 possess a 2D sheet structure including 10-membered rings assembled from four [Cu(pty)]2+ motifs and six [V2O6]2- clusters in 2, and two [Cu(tpy)]2+ units and eight [V2O6]2- clusters in 3. Noteworthy, hybrids 1-3 can be employed as bifunctional electrocatalysts for electroreduction of nitrite and electrooxidation of ascorbic acid. Addnl., theor. calculations including the mol. electrostatic potential and the frontier MO were performed to estimate the electronic structure of hybrids 1-3. The natural bond orbital anal. was also calculated to interpret the electron charge distribution. The experimental part of the paper was very detailed, including the reaction process of 4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3COA of Formula: C20H14N4)
4′-(4-Pyridyl)-2,2′:6′,2”-terpyridine(cas: 112881-51-3) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. COA of Formula: C20H14N4The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds.
