(Azido-κN)bis(di-2-pyridylamine)-copper(II)hexafluorophosphate and (azido-κN)bis(di-2-pyridylamine)-copper(II)-chloridetetrahydrate

The two new title complexes, [Cu(N-3)( dpyam)(2)]PF6 ( dpyam is di-2-pyridylamine, C10H11N3), (I), and [Cu( N-3)(dpyam)(2)]Cl-.-4H(2)O, (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 Fatoms 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.
