Bis(azido-κN)(di-2-pyridylamine-κ2N2,N2′)palladium(II)

In the title complex, [Pd(N3)2(C10H9N3)], the PdII ion is in a slightly distorted square-planar coordination environment. The ligator atoms comprise the two pyridine N atoms of the chelating di-2-pyridylamine (dpa) ligand and two N atoms from two azide anions. The dpa ligand coordinates the Pd atom in a boat conformation, the dihedral angle between the pyridine rings being 24.4 (1)°. The pyridine rings are somewhat inclined to the least-squares plane of the PdN4 unit, making dihedral angles of 29.02 (9) and 26.47 (9)°. The azide ligands are slightly bent, with N—N—N angles of 173.0 (4) and 174.2 (4)°. In the crystal, molecules are connected by N—H...N and C—H...N hydrogen bonds, forming chains along the c axis. When viewed down the b axis, successive chains are stacked in opposite directions. Intramolecular C—H...N hydrogen bonds are also observed.
