title: Dichloridobis[2-(1-hydrazinylideneeth-yl)pyrazine-κN(1)]zinc.
abstract: In the structure of the title complex, [ZnCl(2)(C(6)H(8)N(4))(2)], the Zn(II) atom has a distorted octa-hedral geometry. Two cis Cl(-) ions and four N atoms belonging to two different 2-(1-hydrazinylideneeth-yl)pyrazine ligands coordinate the Zn(II) atom, forming two five-membered Zn-N-C-C-N rings. The dihedral angle between the planes of these metallocycles is 88.13 (4)°. The organic ligands are essentially planar (r.m.s. deviations from planarity = 0.072 and 0.040 Å). Inter-molecular N-H⋯N and N-H⋯Cl inter-actions join the mol-ecules into a three-dimensional framework.
