Key indicators: single-crystal X-ray study; T = 302 K; mean (C-C) = 0.008 Å; R factor = 0.065; wR factor = 0.174; data-to-parameter ratio = 16.4. The title compound, [ZnCl 2 (C 4 H 5 N 3 ) 2 ], contains a fourcoordinate Zn II atom in an approximately tetrahedral environment. The Zn II atom lies on a twofold rotation axis and is coordinated by two N atoms of two 2-aminopyrimidine ligands and by two Cl À anions. N-HÁ Á ÁN hydrogen bonds connect the complex molecules to form a one-dimensional

The supramolecular chains are parallel to each other and N-HÁ Á ÁCl hydrogen bonds link them into a two-dimensional network in the ac plane.
