Dichloridobis[2-(1-hydrazinylideneeth-yl)pyrazine-κN(1)]zinc.

In the structure of the title complex, [ZnCl2(C6H8N4)2], the ZnII atom has a distorted octa­hedral geometry. Two cis Cl− ions and four N atoms belonging to two different 2-(1-hydrazinylideneeth­yl)pyrazine ligands coordinate the ZnII 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 A). Inter­molecular N—H⋯N and N—H⋯Cl inter­actions join the mol­ecules into a three-dimensional framework.
