Redetermination of diaquatris(4-oxopent-2-en-2-olato-κ2O,O′)lanthanum(III)
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]....

| Summary: | 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 La3+ ion is coordinated by three O,O′-bidentate 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 bonds. |
