In the title compound, [V(C15H11O2)2O(CH3OH)]·2CH3OH, the VIV atom is coordinated by two 1,3-diphenylpropane-1,3-dionate ligands and an oxide ligand in an axial position. The sixth position is occupied by the O atom of a methanol group bonded trans to the oxide atom. The octahedral geometry is significantly distorted, with the VIV atom lying 0.330 (3) Å above the equatorial plane formed by the O atoms of the two β-diketonate ligands. In the crystal, O—HO hydrogen bonds between the coordinating methanol group in the complex and the two methanol solvent molecules lead to the formation of polymeric chains along the c-axis direction. Weak C—HO contacts are also observed.

In the title compound, [Rh(C10H9O2)(CO)2], a distorted square-planar coordination geometry is observed around the RhI atom, formed by the O atoms of the bidentate ligand and two C atoms from the carbonyl ligands. The RhI atom is displaced from the plane through the surrounding atoms by 0.017 Å. In the crystal, C—HO interaction is observed between a methyl group of the bidentate ligand and a carbonyl O atom. Metallophilic interactions [3.308 (3) and 3.461 (3) Å] between neighbouring RhI atoms are encountered in the crystal, resulting in the formation of a metal chain along the b-axis direction.

The title compound [systematic name: 5-(trifluoromethoxy)-1H-indole-2,3-dione], C9H4F3NO3, crystallized with two molecules in the asymmetric unit. Intermolecular N—HO hydrogen bonds link the molecules to form layers parallel to the ab plane. In addition, π–π stacking interactions are observed with a centroid–centroid distance of 3.721 (1) Å. The near planarity of the two isatin ring systems is illustrated by by the maximum deviations of 0.023 (1) and 0.025 (1) Å for the N atom in each case.
