摘要：

The title compound (H3tpda)2[CdCl4] (H2tpda = 2,6-bis(2-pyridylamino)pyridi-ne) was synthesized by the reaction of CdCl2 with H2tpda in methanol under acidic condition. Single- crystal X-ray analysis reveals that the compound crystallizes in monoclinic, space group P21/n with a = 13.377(3), b = 16.978(3), c = 14.328(3) ?, β = 94.75(3)°, V = 3243.1(11) ?3, Z = 4, Dc = 1.603 g/cm3, μ = 1.042 mm–1, F(000) = 1576, C30H28CdCl4N10, Mr = 782.82, T = 291(2) K, R = 0.0433 and wR = 0.0848 for observed 4554 reflections with I > 2σ(I). The cadmium(II) atom in the complex anion is tetrahedrally coordinated by four chlorine atoms, whereas, in each [H3tpda]+ cation, one pyridyl nitrogen is protonated. A 3D network is formed by multiple intermolecular hydrogen bonds between the cations and anions as well as π-π interactions among the pyridyl rings.
