The vanadium atoms in the title anion form a spherical shell— “bulged” by As2O5 groups —around an enclosed H2O molecule. This was revealed by an X-ray structure analysis of the salt K6[As6V15O42(H2O)]ṁ8 H2O. The compound is very readily formed and crystallizes in the form of very large, brown rhombohedra.
