K₆H₂[TiW₁₁CoO₄₀]·13H₂O, with a mono­titanoundeca­tungstocobaltate(II) anion

Hexapotassium dihydrogen monotitanoundeca­tungsto­cobalt­ate(II) trideca­hydrate, K₆H₂[TiW₁₁CoO₄₀]·13H₂O, crystallizes from aqueous solution in the cubic space group P3m. The structure was refined as an inversion twin. The [TiW₁₁CoO₄₀]^8- anion has a Keggin structure with one W-atom site occupied by titanium and a central tetra­hedral CoO₄ group.

[2-Carb­oxy-2,2′,2′′-nitrilo­tris(ethanethiol­ato)-κ⁴N,S,S′,S′′](triphenyl­phosphine-κP)rhenium(III) acetone solvate

The title compound, [Re(C₇H₁₂NO₂S₃)(C₁₈H₁₅P)]·C₃H₆O, crystallizes from a solution in chloro­form–acetone–cyclo­­hexane with enantiomers disordered equally over each mol­ecular site. Hydrogen bonds between the carbox­yl groups form dimers in the crystal structure.
