Abstract
This work is concerned with optimisation of reaction conditions of the 3-semikarbazon-2,3-dioxoindole (3-SKIz) reaction with iron ions. It w as observed that chelates of Fe(II) with 3-SKIz show T-c = 810 K and J (s) approx. 5,5.10(-6) Wb.m.kg(-1) and lower, dependent on the measure ment temperature. Similar magnetic parameters of Fe(III) chelates with 3-SKIz are lower of one to two orders.
