The simple and double salts of hexamolybdotelluric(VI) acid, M 3 [TeMo 6 O 24 ] · nH 2 O(NH 4 ) 2x M 3−x [TeMo 6 O 24 ] · mH 2 O, as well as substitutive telluromolybdates MTe y 6+ Mo 1−y O 4 and additive telluromolybdates MTe 4+ MoO 6 , where M = Ni, Mn, Zn, Cu have been prepared. The products of the thermal decomposition of the simple salts of hexamolybdotelluric(VI) acid are the respective substitutive telluromolybdates. MoO 3 , and occasionally molybdates. MMoO 4. The double salts decomposition involves the total reduction of Te 6+ to Te 4+ and the formation of respective molybdates or additive telluromolybdates and MoO 3. The obtained preparations have been characterized by the chemical and X‐ray methods. The substitutive telluromolybdates adopt a wolframitetype structure as the high‐pressure modifications of Co, Ni, Mn, and Zn molybdates reported by Young and Schwarz.
