内容記述タイプ Abstract
内容記述 1. Diammine-dinitro-oxalo-cobalt complex [Co(NH3)2(NO2)2C2O4]Me has been resolved into the optically active isomers by fractionation of the salts of brucine, strychinine and cinchomine. 2. In the fractionation of the alkaloid salts of the complex, either the l-alkaloid-l-cobalt complex or d-alkaloid-d-cobalt complex was always found to separate out as the least soluble fraction, while either the l-alkaloid-d-cobalt complex or d-alkaloid-l-cobalt complex always contituted the most easily soluble fraction. 3. The specific rotations of potassium and ammonium diammine-dinitro-oxalo-cobaltiates, which have been obtained by replacing the alkaloid molecules with potassium-and ammonium ions respectively, were measured, and found to have the values of ca±115°, using sodium light. 4. As a results of the mesotomisation of diammine-dinitro-oxalo-cobalt complex, the configurations of this complex and also of its mother substance, diammine-tetranitro-cobalt complex, have been made clear, the possibility of mesotomisation indicating that the complex ion [Co(NH2)2(NO2)2C2O4] is constructed asymmetrically, which means that the two ammonia molecules in this complex ion occupy the adjacent spacial position. As to the two nitro-groups, their position was previously determined, by one of the authors (Shibata), by a spectroscopic study. 5. The molecular asymmetry of the above mentioned complex ion, which is the first example of a mesotomised complex anion containing a cobalt atom, belongs to a new type and has been introduced into the stereochemistry of the metal complexes, calling it the type of molecular asymmetry III, in extension of Werner's classification. The senior author, Yuji Shibata, has profound sorrow in recording here the death of his collaborator Mr. Toshio Maruki, Rigakushi, which occurred during the progress of the investigation recorded in this paper. At the same time, he has much pleasure in expressing his hearty thanks to Messrs. K. Matsuno, Rigakushi, and S. Mitsukuri for the great assistance they have given him in completing this work.
