Synthesis, structure, solid-state thermolysis, and thermodynamic properties of new heterometallic complex Li{sub 2}Co{sub 2}(Piv){sub 6}(NEt{sub 3}){sub 2}

The reaction of lithium pivalate, polymeric cobalt pivalate [Co(Piv){sub 2}]{sub n}, and triethylamine in THF at 60 {sup o}S afforded the new heterometallic antiferromagnetic complex Li{sub 2}Co{sub 2}(Piv){sub 6}(NEt{sub 3}){sub 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 LiCoO{sub 2}. - Graphical abstract: The solid-state thermolysis, study of the vaporization process, and temperature dependence of S{sub p} for the new heterometallic complex Co{sub 2}Li{sub 2}(Piv){sub 6}(NEt{sub 3}){sub 2} were performed. Decomposition of Co{sub 2}Li{sub 2}(Piv){sub 6}(NEt{sub 3}){sub 2} results in the formation of LiCoO{sub 2}.
