摘要：

The title compounds, hexakis[mu(3)-2-(dimethylamino)ethanolato]hexa- 2-isopropanolato- 4-oxido-tetradecalithium(I), [Li7(i-PrO)3(C4HioN0)3120 (1), and {3-[(2-methoxyethyl)(methyl)amino1-1,1-dimethylpropanolatoldiisopropanolsodium(I), [Na(i-PrOH)2(C8H18NO2)] (2), were crystallized in the presence of 2-propanol (i-PrOH, C3H7OH). The structure 1 has monoclinic symmetry (C2Ic) and the asymmetric unit contains half of the compound. Title compound 2 has triclinic symmetry (Pi) and the asymmetric unit is half of an inversion symmetric aggregate. Both compounds consist of an alkali metal, an aminoalkoxide and a 2-propanol compound. Furthermore, the dimeric sodium aggregate 2 is build up by hydrogen bonding through the 2-propanol and the alkoxides. Compound 1 does not exhibit hydrogen bonding, due to the fact that the 2-propanol is deprotonated. In compound 1, benzene appeared as cocrystallate, but was suppressed by solvent masking because of strong disorder. The formula mass and density do not take account of the solvent.
