Bis(azido-κN)(di-2-pyridylamine-κ2 N 2,N 2′)palladium(II)
نویسنده
چکیده
In the title complex, [Pd(N(3))(2)(C(10)H(9)N(3))], the Pd(II) ion is in a slightly distorted square-planar coordination environment. The ligator atoms comprise the two pyridine N atoms of the chelating di-2-pyridyl-amine (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 PdN(4) 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, mol-ecules 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. Intra-molecular C-H⋯N hydrogen bonds are also observed.

The mononuclear neutral title complex, [Ni(NCS)(2)(C(10)H(9)N(3))(2)], shows a cis-octa-hedral geometry around the Ni(II) ion, formed by two chelating di-2-pyridyl-amine (Hdpa) ligands and two thio-cyanate anions. Both amine H atoms are involved in N-H⋯S hydrogen bonding, resulting in the formation of layers of inter-linked mol-ecules parallel to the ab plane, which are further held together by...
