Synthesis, structure, solid-state thermolysis, and thermodynamic properties of new heterometallic complex Li2Co2(Piv)6(NEt3)2

The reaction of lithium pivalate, polymeric cobalt pivalate [Co(Piv)2]n, and triethylamine in THF at 60 °С afforded the new heterometallic antiferromagnetic complex Li2Co2(Piv)6(NEt3)2 (2). The molecular and crystal structure of complex 2 was established and its magnetic behavior was studied. The vaporization and solid-state thermolysis of 2 were investigated. The thermodynamic characteristics of complex 2 were determined. The results of the present study show that complex 2 can be used as a potential molecular precursor for the synthesis of thin films of lithium cobaltate LiCoO2.

Graphical abstractThe solid-state thermolysis, study of the vaporization process, and temperature dependence of Сp for the new heterometallic complex Co2Li2(Piv)6(NEt3)2 were performed. Decomposition of Co2Li2(Piv)6(NEt3)2 results in the formation of LiCoO2.Figure optionsDownload full-size imageDownload as PowerPoint slide
