Abstract:	The heteronuclear complex [Fe₄Li₂(O)₂(Piv)10(H₂O)₂] (1, Piv is the pivalic acid anion) was obtained by refluxing Fe^III pivalates with Li^I pivalates in toluene and isolated as the 1?PhCH₃ solvate with a toluene molecule. According to X-ray diffraction data, complex 1 contains the {Fe₄Li₂O₂} core. The Mössbauer spectroscopy data indicate that the core comprises para magnetic Fe^III ions in the high-spin state located in the symmetric octahedral environment of oxygen atoms. Thermolysis of 1 studied by simultaneous thermal analysis demonstrated thermal stability of the complex up to 225 °С. The main end product of thermolysis at 600 °С is the mixed oxide LiFe₅O₈.
