Copper(II) assisted hydrolysis of 2,4,6-tris(pyrazol-1-yl)-1,3,5-triazine. Crystal and molecular structure of catena-[CuL(H2O)Cl] n (L=2,4-dione-1,3,5-(1H)-triazin-1-amido)

Abstract: This article describes the partial hydrolysis of the multidentate ligand 2,4,6-tris(pyrazol-1-yl)-1,3,5-triazine in the presence of copper(II), to give the anionic ligand 2,4-dione-1,3,5-(1H)-triazin-1-amido, which was isolated as the cupric complex catena-[CuL(H2O)Cl] n , where L is the amido ligand. No other hydrolysis products were isolated or identified. The complex defines a zigzag 1D covalent chain, along the b cell axis, through apical copper–oxygen bonds (Cu–N–C–O···Cu bridges).
