Redetermination of diaquatris(4-oxopent-2-en-2-olato-κ2 O,O′)lanthanum(III)

چکیده
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,O'-bidentate acetyl-acetate (acac(-)) ligands and two water mol-ecules, resulting in a fairly regular square-anti-prismatic LaO8 coordination geometry, with both aqua ligands part of the same square face. In the crystal, the neutral complex mol-ecules are linked into [110] chains by O-H⋯O hydrogen bonds.

The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinu...

The title structure, {[Ba(0.71)Sr(1.29)(C(4)HO(4))(4)(H(2)O)(10)]·H(2)O}(n), is built from dimers of edge-sharing monocapped square anti-prisms [(Ba/Sr)O(3)(H(2)O)(6)], in which barium and strontium are statistically disordered [ratio 0.353 (8):0.647 (8)] on the same crystallographic site. Such dimers are connected via bidentate hydrogen squarate groups [HC(4)O(4)](-), leading to chains that pr...

In the title complex, [Co(C(16)H(15)N(2)O)(C(10)H(9)O(2))(N(3))], the Co(II) atom adopts an octa-hedral coordination geometry by a tridentate Schiff base, a bidentate benzoyl-acetonate and an azide ligand. The imine N atom of the tridentate ligand is trans to the benzoyl O atom of the bidentate ligand and the azide ligand is trans to the acetyl O atom of the bidentate ligand. Non-classical intr...

In the crystal structure of the title compound, [Co(C(2)H(4)NO(2))(C(9)H(6)NO)(2)]·CH(3)OH, the Co(III) atom is chelated by two quinolin-8-olate and one glycinate anions in a distorted octa-hedral coordination geometry. The five-membered chelating glycinate ring assumes an envelope conformation. The complex mol-ecules are assembled by inter-molecular N-H⋯O hydrogen bonding.
