A₆Mo₂P₄O₁₉ (A = Rb, Cs) and Rb₂MoP₂O₉: new molybdophosphates with distinct polyanionic configurations

Abstract

The exploration in the A-Mo-P-O (A = Rb, Cs) systems has allowed several new Mo(V) phosphates, Rb2MoP2O9, Rb6Mo2P4O19 and Cs6Mo2P4O19 synthesized through the spontaneous nucleation method. Single-crystal X-ray diffraction analysis...

K2MgMoP2O10 and K3Mg2MoP3O14: two new molybdophosphates exhibiting different optical anisotropies induced by variable dimensionality of the anion framework

“…In the structure of molybdophosphates, [MoO 6 ] and [PO 4 ] units are often connected to produce different structures, such as zero-dimensional (0D) Mo–O–P clusters, 32,33 1D Mo–O–P chains, 34 and 2D Mo–O–P layers. 34–40 Successful examples with new structures and special performances have been reported, such as KCsMoP 2 O 9 , 41 Cs 4 Mo 5 P 2 O 22 , 42 Cs 3 Mo 12 PO 40 , 43 Sr(MoPO 6 ) 2 , 43 Rb 2 Bi(MoO 4 )(PO 4 ), 44 Cs 6 Mo 2 P 4 O 19 , 45 and so on. Therefore, it is of great significance to study the structural evolution and properties of Mo–P–O systems.…”
