四-(邻氯苯基)卟吩及其金属络合物的红外光谱
THE INFRARED SPECTRA OF TETRAKIS-(ORTHO-CHLOROPHENYL)PORPHIN AND ITS METALLOCOMPLEXES
【摘要】 测试研究了四-(邻氯苯基)卟吩其Mg(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Zo(Ⅱ)、Cd(Ⅱ)、Mn(Ⅲ)和In(Ⅲ)络合物的4000—100cm-1范围红外光谱。3330和795cm-1谱带起源于H2(O-Cl-TPP)的N—H振动,1130和1070cm-1谱带与苯环上的C—Cl振动有关。金属敏感谱带出现在1340、1010、450、340和230cm-1等附近。络合物的1520cm-1附近谱带频率可能由于金属离子质量的影响按Mg(Ⅱ)>Zn(Ⅱ)>Cd(Ⅱ)递减,230cm-1附近谱带频率按Co(Ⅱ)>Ni(Ⅱ)>Cu(Ⅱ)>Mg(Ⅱ)>Mn(Ⅲ)>Zn(Ⅱ)~Cd(Ⅱ)>In(Ⅲ)顺序递减。
【Abstract】 The infrared spectra in the range of 4000—100cm-1 of tetrakis-(ortho-chlorophenyl)porphin and its Mg(Ⅱ), Co(Ⅱ), Ni(Ⅱ), Cu(Ⅱ), Zn(Ⅱ), Cd(Ⅱ), Mn(Ⅲ) and In(Ⅲ)-complexes have been measured and investigated. Bands at 3330cm-1 and 795cm-1 are N-H vibrations and those at 1130cm-1 and 1070cm-1 result from monochloro-substitution on phenyl rings of o-Cl-TPP compounds. Metal sensitive bands have been found at 1340cm-1, 1010cm-1, 450cm-1 and 230cm-1. Bands at 1520cm-1 of M(o-Cl-TPP)-decrease in wave number as Mg (Ⅱ)(1525)>Zn(Ⅱ)(1522)>Cd(Ⅱ)(1512)possibly because of mass effect of central metal ions and bands at~230cm-1 have the sequence of Co(Ⅱ)(291)>Ni(Ⅱ) (261)>Cu(Ⅱ)(250)>Mg(Ⅱ)(240)>Mn(Ⅲ)(236)>Zn(Ⅱ)(235)~Cd(Ⅱ)(235)>In(Ⅲ)(206).
