The structure of catena-poly[[[di-μ-acetato-1:2κ4O:O'-diaqua-2κ2O-calciumcopper]-di-μ-acetato-1:2'κ4O:O] hexahydrate], originally determined twice at room temperature, has been redetermined at 173K. There are no significant differences between these structures.

In the crystal structure of the title taxoid, taxa-4(20),11-diene-2α,5α,10β,14β-tetrayl 2α,5α,10β-triacetate 14β-(2-methylbutyrate), left-hand ring A has a distorted boat, central ring B a boat–chair and right-hand ring C a distorted chair conformation. The terpenoid core is folded in a cage-type conformation, with the butyrate side chain in a trans,trans,gauche,gauche,trans conformation.

The crystal structure of dicalcium bis(oxonium) decavanadate hexadecahydrate has been determined by X-ray analysis. The main feature of the structure is the [V10O28]6- anion, built up from ten distorted edge-sharing VO6 octahedra with well established structures. Each Ca2+ ion is surrounded by seven water molecules in the form of a distorted pentagonal bipyramid.
