Abstract
In the title complex, [Pt(N3)4(C10H9N3)], the PtIV ion is six-coordinated in a slightly distorted octahedral environment by the two pyridine N atoms of the chelating di-2-pyridylamine (dpa) ligand and four N atoms from four azide anions. The dpa ligand is not planar, the dihedral angle between the pyridine rings being 20.0 (3)°. The azide ligands are slightly bent [N—N—N = 173.5 (8)–175.1 (8)°]. In the crystal, the complex molecules are connected by N—H⋯N hydrogen bonds, forming a chain along the b axis. An intermolecular π–π interaction between the chains is also present, the ring centroid–centroid distance being 3.713 (4) Å.
Highlights
Kwang HaR factor = 0.036; wR factor = 0.077; data-to-parameter ratio = 12.8
The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2
