Tris(2-formyl­phenolato-κ²O,O′)(1,10-phenanthroline-κ²N,N′)samarium(III)

In the title compound, [Sm(C₇H₅O₂)₃(C₁₂H₈N₂)], the Sm^III cation is coordinated by six O atoms from three bidentate 2-formyl­phenolate ligands and by two N atoms from 1,10-phenanthroline ligand. The resulting SmN₂O6 coordination polyhedron is a distorted square anti­prism. In the crystal, C—H...O inter­actions connect mol­ecules into chains along the b-axis direction. In addition, π–π stacking inter­actions are observed with centroid–centroid distances in the range 3.6422 (13)–3.7329 (13) Å.

N-(2,6-Dimeth­oxy­pyridin-3-yl)-9-methyl-9H-carbazole-3-sulfonamide

In the title compound, C₂₀H₁₉N₃O₄S, a novel tubulin ligand active against human cancer, the dihedral angle between the pyridine ring and the carbazole ring system is 42.87 (10)°. In the crystal, the mol­ecules are held together by N—H...O and C—H...O hydrogen bonds into layers, which are assembled into a three-dimensional network via π–π stacking inter­actions between inversion-related pyridine rings, with centroid–centroid distances of 3.5101 (12) Å.
