  "abstract": "The reaction of lithium metal with dry N,N-di-methyl-acetamide produced crystals of catena-poly[(μ3-N,N-di-methyl-acetoacetamidato)lithium(I)], [Li(C6H10NO2)] n , (I), which crystallizes as a coordination polymer with a chain of fused Li2O2 rings. A similar reaction of lithium metal with N,N-tetra-methyl-urea produces crystals of hexa-kis-[μ3-1,2-bis-(di-methyl-amino)-2-oxo-ethan-1-olato]hexa-lithium(I), [Li6(C6H13N2O2)6], (II), which crystallizes as a hexa-mer, with the alkoxide O atoms in a Li6O6 barrel-shaped cluster with threefold symmetry, and the keto O atoms bonded to the lithium atoms outside the cage.",
