Sodium‐tetramethylammonium decamolybdate 3.5‐hydrate was investigated in the range of 77 to 293 K by X‐ray diffractometric and wide‐line proton magnetic resonance and IR techniques. At low temperatures the compound undergoes transitions connected with change of reorientations of CH 3 , H 2 O and (CH 3 ) 4 N + groups.
