Abstract

In the crystal of the title compound, [ZnCl(2)(C(5)H(5)N(3)O)(2)], the mol-ecule has m symmetry, with the Zn(II) cation and Cl(-) anions located on the mirror plane. The Zn(II) cation is coordinated by two Cl(-) anions and two pyrazine-2-carboxamide ligands in a distorted ZnCl(2)N(2) tetra-hedral geometry. The two pyrazine rings are nearly perpendicular to each other [dihedral angle = 86.61 (10)°]. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds and weak C-H⋯O inter-actions stabilize the crystal packing.
