(Azido-[kappa]N)bis­(di-2-pyridylamine)­copper(II) hexa­fluoro­phosphate and (azido-[kappa]N)bis­(di-2-pyridylamine)­copper(II) chloride tetra­hydrate

The two new title complexes, [Cu(N₃)(dpyam)₂]PF₆ (dpyam is di-2-pyridylamine, C₁₀H₁₁N₃), (I), and [Cu(N₃)(dpyam)₂]Cl·4H₂O, (II), respectively, have been characterized by single-crystal X-ray diffraction. Both complexes display a distorted square-pyramidal geometry. Each Cu atom is coordinated in the basal plane by three dpyam N atoms and one azide N atom in equatorial positions, and by another N atom from the dpyam group in the apical position. In complex (I), the one-dimensional supra­molecular architecture is assembled via hydrogen-bonding inter­actions between the amine N atom and terminal azide N atoms and the F atoms of the PF₆^- anion. For complex (II), hydrogen-bonding inter­actions between the amine N atom, the Cl^- anion and water O atoms result in a two-dimensional lattice.
