The vanadium atoms in the title anion form a spherical shell — “bulged” by As 2 O 5 groups —around an enclosed H 2 O molecule. This was revealed by an X‐ray structure analysis of the salt K 6 [As 6 V 15 O 42 (H 2 O)]ṁ8 H 2 O. The compound is very readily formed and crystallizes in the form of very large, brown rhombohedra.
