Single‐crystals of the polar compound magnesium hydrogen vanadate(V), Mg 13.4 (OH) 6 (HVO 4 ) 2 (H 0.2 VO 4 ) 6 , were synthesized hydrothermally. It represents the first hydrogen vanadate(V) among inorganic compounds. Its structure was determined by single‐crystal X‐ray diffraction [space group P 6 3 mc , a = 12.9096(2), c = 5.0755(1) Å, V = 732.55(2) ų, Z = 1]. The crystal structure of Mg 13.4 (OH) 6 (HVO 4 ) 2 (H 0.2 VO 4 ) 6 consists of well separated, vacancy‐interrupted chains of face sharing Mg2O 6 octahedra, with short Mg2—Mg2 distances of 2.537(1) Å, embedded in a porous magnesium vanadate 3D framework having the topology of the zeolite cancrinite. All three hydrogen positions in the structure were confirmed by FTIR spectroscopy. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
