Lithium 3-trifluoromethyl-1,3-diketonates containing pyridyl substituents were synthesized. The specific features of the crystal structures of lithium (Z)-1,1,1-trifluoro-4-oxo-4-(pyridin-3-yl)- and (Z)-1,1,1-trifluoro-4-oxo-4-(pyridin-4-yl)but-2-en-2-olates were revealed by X-ray diffraction. These compounds have a polymeric structure with lithium cations in different coordination modes. The 1,3-diketonate group is involved in chelation and formation of oxygen bridges, thereby linking two types of lithium atoms.
