ON THE DIOXIMINE COMPLEXES OF TRANSITION METALS, Part XC NEW AZIDO-COMPLEX ACIDS OF COBALT(III) WITH ALICYCLIC α-DIOXIMES

Four new diazido-complex acids of the type H[Co(Diox.H)2(N3)2] (Diox.H2 = alicyclic α-dioximes: Cpdox.H2, Niox.H2, Heptox.H2 and Octox.H2) and the H[Co(Niox.H)2(N3)(NO2)] were obtained by air oxidation of the components and by sub- stitution reactions. The free acids and their salts were characterized by IR and electronic spectra and by potentiometric measurements. The composition of the azido-derivatives was proved also by isolation of 30 new salts with cobalt(III)- and chromium(III)- amine bases.
