摘要：
Iron(III) and cobalt(III) complexes of types [Fe(LEt)2]ClO4·3/2C6H6 (1) and [Co(LEt)2]ClO4·2CH2Cl2 (2) with a new pyrimidine-derived thiosemicarbazone ligand, 2-S-methyl-6-methyl-4-formylpyrimidine-N(4)-ethylt-hiosemicarbazone (HLEt), having N, N, S donor centers have been synthesized and characterized by X-ray crystallography. The structural study shows distorted octahedral geometry for both 1 and 2 with MN4S2 chromophores. The space group of 1 is C2/c (monoclinic) and that of 2 is P212121 (orthorhombic). The electrochemical electron transfer study in MeCN solutions shows a one-electron reductive response presumably due to a metal(III)–metal(II) couple.
