The first coordination complex of (5 R ,6 R ,7 S )-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-(5 R ,6 R ,7 S )-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(C 2 H 3 O 2 )Cl(C 15 H 15 N 5 O)]·H 2 O} 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.
