摘　　要：本文研究了以烷氧桥相连的四苯基铁（Ⅲ）锌（Ⅱ）双卟啉系列化合物的傅里叶变换红外光谱。对一些主要吸收谱带进行了经验归属。卟啉环的结构敏感谱带出现在１５２４（以ＦｅＰ－ＺｎＰ为例），１５０９，１４７２，１３９０，１３３９，１００３，９９５，８８２，８４１，８３３和７９８ｃｍ－１附近，Ｆｅ－Ｃｌ伸缩振动在３６２ｃｍ－１附近，Ｆｅ－Ｎ与卟啉环的复合振动在２７９ｃｍ－１附近，Ｚｎ－Ｎ与卟啉环的复合振动在２４７和２０６ｃｍ－１附近。通过一些特征谱带的分析，认为以烷氧桥相连的四苯基铁（Ⅲ）锌（Ⅱ）双金属卟啉化合物在固态下以＂面－面＂构象方式存在。The FTIR spectra (3600--150cm-1 of Fe (Ⅲ) Zn (Ⅱ) bis--tetraphenylporphyrin dimers linked by a flexible alkoxy chain were measured and investigated. The major bands have been empirically assigned in comparison with a large number of porphyrins and metalloporphyrin complexes.The structure--sensitive bands of the porhhyrin ring were found at 1524, 1509, 1472,1390,1339,1003,995,882, 841, 833 and 798cm-1. The νFe-Cl was at 362cm-1. The vibration coupling between the Fe--N stretching and the porphyrin ring deformation was at 279cm-1.The vibration coupling between the Zn--N stretching and the porphyrin ring deformation was at 247 and 206cm-1. By the combination of the assignments, it can be concluded that the conforrnation of these metalloporphyrin dimers is 'face to face' in solid state.
