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

Abstract

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.
