Unusual in the polyoxometalate 1 are the hydrogen squarate ions and the presence not only of edge‐sharing but also corner‐sharing octahedra. An identification of the protonated sites was not possible, but an elemental analysis and the IR spectrum unequivocally confirm the presence of protons. Crystals of the Bu 4 N‐salt of 1 , which crystallizes with ten Et 2 O molecules per formula unit, readily lose two of the Et 2 O molecules; therefore the X‐ray structure analysis had to be carried out in the presence of mother liquor.
