Dichloridobis{1-[(2-methyl­benzimidazol-1-yl-κN³)meth­yl]benzotriazole}zinc

The title mononuclear Zn^II complex, [ZnCl₂(C₁₅H₁₃N₅)₂], is isotypic with the previously reported Hg^II complex. The Zn^II atom is located on a twofold rotation axis and has a distorted tetra­hedral environment of two Cl atoms and two N atoms from two heterocyclic ligands. In the crystal, complex mol­ecules are extended by inter­molecular π–π inter­actions [centroid–centroid distance = 3.792 (2) Å] into a three-dimensional supra­molecular network.

2-(4-Meth­oxy­phen­oxy)acetohydrazide

The title compound, C₉H₁₂N₂O₃, was synthesized by the reaction of ethyl 2-(4-meth­oxy­phen­oxy)acetate with hydrazine hydrate in ethanol. In the acetohydrazide group, the N—N bond is relatively short [1.413 (2) Å], suggesting some degree of electronic delocalization in the mol­ecule. In the crystal, mol­ecules are linked into sheets lying parallel to the ab plane by N—H...N and N—H...O hydrogen bonds.
