Di-μ-azido-bis­({N′-[1-(2-pyrid­yl-κN)ethyl­idene]acetohydrazidato-κ2 N′,O}dicopper(II))

The dimeric title compound, [Cu2(C9H10N3O)2(N3)2], is located on a crystallographic inversion center. The Cu atom is coordinated by a tridentate anionic hydrazone ligand and two bridging azide ligands in a distorted square-pyramidal coordination geometry. The non-bonding Cu⋯Cu distance is 3.238 (1) Å. Non-classical inter­molecular C—H⋯N hydrogen bonds link the dimers into chains along the c axis

Dichlorido{N′-[1-(2-pyridin-2-yl)ethyl­idene]acetohydrazide-κ2 N′,O}copper(II)

In the title compound, [CuCl2(C9H11N3O)], the CuII atom is in a distorted square-pyramidal CuCl2N2O coordination geometry. The tridentate acetohydrazide ligand chelates in a meridional fashion. The chloride ligand in the axial position forms a long Cu—Cl distance of 2.4892 (9) Å. In contrast, the Cu—Cl distance from the equatorial chloride ligand is much shorter [2.2110 (7) Å]. Inter­molecular N—H⋯Cl and C—H⋯Cl hydrogen bonds link the complexes into a three-dimensional network
