Dichloridobis[2-(1-hydrazinylideneeth-yl)pyrazine-?N(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.
