卟啉化合物的研究　Ⅻ．双核双环钴卟啉配合物轴向配合性质的研究

STUDY ON PORPHYRIN COMPOUNDS Ⅻ.Study on Axial Coordination Properties of Dicobalt Porphyrin Complexes

报导了用分光光度法测定双核钴（Ⅱ）卟啉与有机碱反应的平衡常数及组成比，并研究了双核钴卟啉与ＣＯ的轴向配位作用，结果表明，双核钴卟啉与ＣＯ的结合是可逆的．用红外差谱法测得ＣＯ的伸缩振动频率是１９５９ｃｍ－１．

Equilibrium constants and component ratio of reaction of dicobalt porphyrin complexes with organic bases were measured by spectrophotometric method. The adduct of dicohalt porphyrin with CO were studied. Experimental resultS show that the adduct reaction is reversible. The CO stretching vibration frequency 1959 cm1 was obtained by using IR differential spectrum method.
