Abstract

In the title complex, [Zn(NCO)2(C7H8N4)2], the ZnII ion exhibits a distorted tetrahedral coordination geometry. The coordination environment is formed by two 5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine (dmtp) ligands, coordinated through the N atom in position 3, and two cyanate anions interacting by their N atoms. Supramolecular dimers are generated by stacking interactions between the pyrimidine rings of two ligands related by an inversion center [centroid-centroid distance = 3.5444 (18) Å].
