Item Synthesis, characterization, and redox potential properties of a new double-stranded Ni-bis(hydrazone)-based helicate(Academic Press Inc., 2020-08-25) Villada, Juan D.; Carmona Vargas, Christian C.; Alcides Ellena, Javier; Ayala, Alejandro P.; Ramírez Pradilla, Juan S.; Combariza, M. Y.; Galarza, Esperanza; D'Vries, Richard Fernando; Chaur, Manuel N.Herein we report the synthesis and structural characterization of a new Ni-bis(hydrazone) complex with the chemical formula [Ni2(L)2(Cl)2](Cl)2·2H2O (L = 2-(heptylthio)-4,6-bis(2-((E)-pyridin-2-ylmethylene)hydrazineyl)pyrimidine). Suitable crystals for X-ray diffraction showed the supramolecular interactions of this complex to exhibit a helical structure coordinating two Ni2+ metal ions bounded by two 2-(heptylthio)-4,6-bis(2-((E)-pyridin-2-ylmethylene)hydrazineyl)pyrimidine ligands. In addition, exploitation of the electrochemical properties by cyclic voltammetry, for this helicate, showed catalyzing ability for the reduction of H+ to H2.
