A new triazine bearing a pyrazolone group capable of copper, nickel, and zinc chelation.

ABSTRACT: Interests in inorganic applications of triazines is growing. In this report, metal complexes of copper(II), nickel(II), and zinc(II) and a novel class of chelates comprising a triazine ring substituted with a hydrazine group and pyralozone are evaluated using spectrophotometric methods, single crystal X-ray diffractometry, and electrochemistry. Complexes with copper(II) include a single chelate and two chloride atoms to satisfy a trigonal bipryamidal coordination sphere. The nickel(II) and zinc(II) complexes are comprised of two chelating groups that adopt an octahedral geometry around the metal ion. Irreversible redox activity was observed with the copper(II) complex but no redox activity was observed with the ligand alone or zinc(II) and nickel(II) complexes. Use of the coumarin carboxyl
