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

The structure of the title compound, [La(C(5)H(7)O(2))(3)(H(2)O)(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....

description The structure of the title compound, [La(C(5)H(7)O(2))(3)(H(2)O)(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,O′-bidentate acetyl­acetate (acac(−)) ligands and two water mol­ecules, resulting in a fairly regular square-anti­prismatic LaO(8) 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.
