Introduction The heteropoly compounds containing molybdenum together with vanadium as Keggin polyanion-[PV x Mo 12− x O 40 ] −(3+ x ) (noted PVMo) are very interesting for catalysis due to their simultaneous acidic and redox
attributed to [PW 12 O 40 ] 3− , and the peak at −13.4 ppm can be attributed to lacunary Keggin-type structure of [PW 11 O 39 ] 7− [ 19 ]. In the range of −3 to +6 ppm, a lot of peaks appear and can be ascribed to the identified species such as [(PO 4 ){WO
, 7 , 12 , 13 , 24 ], but samples of the system AMP/oxide have not been earlier prepared via these methods. Experimental Reagents and materials (NH 4 ) 3 PMo 12 O 40 ·4H 2 O (AMP) powder with specific
friendly catalysts for the polymerization of α -pinene attracts special industrial interest. Heteropolyacids (HPAs), such as H 3 PW 12 O 40 (PW 12 ), H 3 SiW 12 O 40 (SiW 12 ) and H 3 PMo 12 O 40 (PMo 12 ) attract increasing attention worldwide
