- Abstract
TRIS-O,PHENANTHROLINE rutheniumII perchlorate dihydrate1, Ru(phenan)3(ClO4)2.2H2O, has been resolved through the antimonyl tartarate to give [α]D20 = + 979° and − 971° and [α]546·120 = + 1869° and − 1863° for the ion Ru(phenan)3++. Burstall2 found [α]579·125 = + 860° and − 815° for the compound Ru(dipy)3I2.2H2O. The orange-red active perchlorates in 6 normal sulphuric acid were oxidized with cerie nitrate to yield the optically active blue ion Ru(phenan)3+++, for which [α]D20 = + 311° and − 303° and [α]546·120 = + 1,246° and − 1,256°. Reduction of the unstable oxidized ion with ferrous sulphate regenerated the rutheniumnII complex with its rotation unchanged. It is evident that both the di- and tri-valent ruthenium complexes have a very large abnormal rotatory dispersion.
