The structure was determined by single crystal X-ray diffraction and the crystal was monoclinic with space group P21 / n, a = 9.810 (2), b = 14.516 (3), c = 17.008 (3) , V = 2377.2 (8) ?, Z = 4, Mr = 427.52, Dc = 1.195 g / cm3, m (MoKa) = 0.082 mm-1 and F (000) = 920. The crystal structure is solved by the direct method, and the atomic parameters are corrected by full matrix least square method. The final deviation factor is R = 0.0406 and wR = 0.0892. The results of X-ray diffraction analysis showed that the pyridine ring and the two six-membered rings fused to them were all enveloping conformations.
