meso-四-(4-甲氧基苯基)卟啉的晶体和分子结构

CRYSTAL AND MOLECULAR STRUCTURE OF MESO TETRA(4 METHOXYLPHENYL)PORPHYRIN

用Ｘ—射线测定了ｍｅｓｏ－四（４－甲氧基苯基）卟啉的溶剂合物（ＴＰＭＰ·ＣＨＣｌ３）的晶体结构。实验表明，该晶体属单斜晶系，空间群Ｐ２１／Ｃ，ａ＝１．４３７７（２）ｎｍ，ｂ＝０．９６７４（７）ｎｍ，ｃ＝１．５６８８（４）ｎｍ，β＝１０１．００（２）°，Ｖ＝２．１４２ｎｍ３，Ｚ＝２，ｄｃ＝１．３２４ｇ／ｃｍ３，μ＝２．６１３ｃｍ－１，Ｆ（０００）＝４４４。讨论了分子结构中的非平面共轭效应及卟啉环与锰（Ⅲ）离子配位后锰（Ⅲ）对其结构参数的影响。

Crystal and molecular structure of meso tetra(4 methoxylphenyl)porphyrin(TPMP.CHCl 3) have been determined by single crystal X ray diffraction technique.The crystal is monoclinic,space group P 21/C ,a=1.4377(2),b=0.9674(7),c=1.5688(4) nm ,β=101.00(2)°,V=2.142 nm 3,Z=2,d c=1.324g/ cm 3,μ=2.613 cm -1 ,F (000)=444.The structure is solved by the direct method and the Fourier techniques.Effect of the manganese(Ⅲ) ion inserting in prophyrin ring on the structural parameters of porphyr...
