Abstract
The formation of Cd(II) complexes with alkyl thioureas $(Tu=H_2NCSNH_2, CH_3Tu, C_2H_5Tu, C_4H_9Tu)$ has been studied in aqueous solution. Basing on CV and polarographic results the 2-electrons reversible mechanism was assigned. With the aid of POLAG (nonlinear least squares iterative program) the overall stability constants $(log \beta\ _n=1-4)$ were estimated. The values of LUMO energy, heat of formation and electrostatic potential minima were obtained on the basis of quantum-chemical calculations. They confirmed the ealier established stability sequence of Cd(II) complexes with alkyl thioureas, namely $Tu<CH_3Tu<C_2H_5Tu<C_4H_9Tu$. The estimation of $E _\frac {1}{2} $ for 1:1 and 1:4 complexes was made by linear regression.
