摘要：

The structure of the title compound, [La( C5H7O2) (3)( H2O) (2)], has been redetermined to modern standards with anisotropic displacement parameters for all non-H atoms and the hydrogen-bonding pattern unambiguously established [for the previous study, see Phillips et al. (1968). Inorg. Chem. 7, 2295-2299]. The La 3(+) ion is coordinated by three O, O0bidentate acetylacetate (acac (-)) ligands and two water molecules, resulting in a fairly regular square-antiprismatic LaO8 coordination geometry, with both aqua ligands part of the same square face. In the crystal, the neutral complex molecules are linked into [110] chains by O-H...O hydrogen
