摘要: 细胞色素P-450在生物体内温和条件下活化分子氧,选择地催化氧化很不活泼的碳氢化合物。铬(Ⅲ)卟啉配合物在温和条件下以亚碘酰苯或过氧羧酸等为氧化剂可选择性地催化氧化碳氢化合物,是细胞色素P-450的很好的模型化合物[1],但目前得到的铬(Ⅲ)卟啉配合物为数尚少。本文在三氯甲烷中用氧化-还原法从一氯四苯基卟啉合铬(Ⅲ)(配合物Ⅰ)合成了迭氮基吡啶四苯基卟啉合铬(Ⅱ)(配合物Ⅱ),培养了配合物Ⅱ的单晶,x-射线四圆衍射法测定了其晶体和分子结构。这是第一个得到的三价铬四苯基卟啉的分子结构。

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
