The first coordination complex of (5R,6R,7S)-5-(furan-2-yl)-7-phenyl-4,5,6,7-tetra-hydro-[1,2,4]triazolo[1,5-a]pyrimidin-6-amine with zinc(II) acetate-chloride.

The title complex, systematic name catena-poly[[[acetato-chlorido-zinc(II)]-μ-(5R,6R,7S)-5-(furan-2-yl)-7-phenyl-4,5,6,7-tetra-hydro-[1,2,4]triazolo[1,5-a]py-rimi-din-6-amine] monohydrate], {[Zn(C2H3O2)Cl(C15H15N5O)]·H2O} n , is the first coordination complex in which the neutral tetra-hydro-triazolo-pyrimidine derivative acts as bridging ligand between two zinc mol-ecules. As a result, polymeric chains of the coordination complex are found. The coordination of the zinc metal atom occurs with the lone pairs of the triazolo nitro-gen atom and amino group. The positive charge of the zinc atom is compensated by the chlorine anion and deprotonated acetic acid. The coordination complex exists as a monohydrate in the crystalline phase. The water mol-ecules bind neighbouring polymeric chains by the formation of O-H⋯O, O-H⋯Cl and N-H⋯O hydrogen bonds. © Shyshkina et al. 2021.
