| Abstract: | The solid-state thermolysis (420–450 °С) of the new heterometallic coordination polymer Li2Co2(Piv)6(μ-L)2]n (1, Piv is the anion of pivalic acid, L is 2-amino-5-methylpyridine) followed by annealing of the decomposition products at 500 °С was shown to afford LiCoO2 in quantitative yield. Compound 1 was characterized by X-ray diffraction and magnetic measurements. |
