Tris(2-N-methyl­amino­carbonyl-3-hydr­oxy-1,6-dimethyl-1,4-dihydro-4-pyridinonato)­iron(III) dimethyl­formamide disolvate

In the crystal structure of the title compound, Fe(C₉H₁₁N₂O₃)₃·2C₃H₇NO, the Fe^III ion is six-coordinate with a distorted octa­hedral configuration consisting of six donor O atoms from three bidentate ligands. Two of the amide NH groups are involved in intra­molecular N—H...O_p (p = phenolic) hydrogen bonds, while the third is involved in forming centrosymmetric dimers via inter­molecular N—H...O_p hydrogen bonds.

Tris(1-cyclo­propyl-6-methyl-2-(N-methyl­amino­carbonyl)-4-oxo-1,4-dihydro­pyridin-4-olato)iron(III) dimethyl­formamide sesquisolvate dihydrate

In the crystal structure of the title compound, [Fe(C₁₁H₁₃N₂O₃)₃]·1.5C₃H₇NO·2H₂O, the Fe^III ion is six-coordinated in a distorted octa­hedral configuration consisting of six donor O atoms from three bidentate ligands. The Fe complex crystallizes with two mol­ecules of water and one and a half mol­ecules of dimethyl­formamide (DMF). The three amino­carb­oxy groups (CONHCH₃) are all rotated out of the planes of their respective pyridinone rings. Inter­molecular O—H...O and N—H...O hydrogen bonds contribute to the stabilization of the crystal structure.
