Abstract

Reactions 4-7 do take place but none was faster than eq 3. More importantly, however, reactions 4-7 occur at the same rate as eq 3. These facts suggest that B may be an intermediate which either reverts to the six-coordinate complexes A and C or possibly dissociates forming N2O3 (NO+ NO2) and Fe (S2CN (CH3) 2) 2 with the position of equilibrium lying well on the side of B. Species B should be accessible because the { ...
