title: Bis(2-amino-pyrazine-κN)dichlorido-zinc.
abstract: In the title adduct, [ZnCl(2)(C(4)H(5)N(3))(2)], the Zn(II) atom lies on a twofold rotation axis that relates one Cl atom to the other as well as one 2-amino-pyrazine ligand to the other; the coordination geometry is a distorted tetra-hedron. In the crystal, adjacent mol-ecules are linked by N-H⋯N hydrogen bonds across the center of inversion, generating a chain; neighboring chains are linked by N-H⋯Cl hydrogen bonds, forming a three-dimensional network.
