We report a study on the structure directing effects of functional groups and
counterions. The aim was to find a facile and high yielding synthetic
procedure to obtain polyoxometalate (POM) building blocks for post-
functionalisation. Therefore, solvothermal reactions of VOSO4 with various
tris(hydroxymethyl)methane derivatives in alkaline methanolic solutions were
investigated. In doing so, new POM fragments were isolated and characterised.
The binding modes of the functionalised tripodal alkoxides turned out to be
