Abstract: The crystal structure of Cr(Ⅲ) TPP (N3) Py was determined on a Nicolet R3m/E four-circle diffractometer with X-ray intensity data being collected in 3.0°<2θ<34°.The spacegroup is P21/n with a=13.032(4)Å, b = 23.689(5)Å, c= 14.906(2)Å, β= 103.67°, Z = 4.The structure was solved by heavy atom method and Fouirer techniques, and refined byblockdiagonal matric least-squares to a final R = 0.050.Bond distances are as follows:Cr-NN3 2.004Å; Cr-Npy 2.135Å; the average Cr-NPyrrole 2.031Å.

Key words: porphyrin complex, crystal structure, X-ray diffractometry, azido chromium(Ⅲ)tetraphenylporphyrin pyridine complex
