Na3[Al2B6P4O22(OH)3](H2O)6 and Na3[Al2BP2O11](H2O)0.5: Two Remarkable Complex Aluminum Borophosphates

“…A number of borophosphate materials have been prepared, for example, M 2 BP 3 O 12 (M = Fe, Cr) shows interesting magnetic properties, Ba 8 {Ni, Mn} 4 [BP 3 O 11 (OH) 2 ] 4 has a new “anti-zeolite” structure with a positively charged framework, MBPO 5 (M = Sr and Ba), Na 3 Cd 3 B­(PO 4 ) 4, AMBP 2 O 8 (A = K, M = Sr, Ba; A = K, Rb, M = Pb), − and β-Zn 3 (BO 3 )­(PO 4 ) are potential nonlinear optical materials. The Eu 2+ -doped Ba 3 BP 3 O 12 is a new scintillation material .…”

New types of open-framework vanadium borophosphates with photocatalytic properties

“…Vanadium borophosphates have attracted significant interest in their abundant structures and important physicochemical properties. 21 Most vanadium borophosphates are hydrothermally synthesized in the presence of organic amines, 22–31 alkali–metal ions, 32,33 or metal complexes, 34–39 which serve as templates or structure-directing agents, significantly affecting the frameworks of inorganic vanadium borophosphates. Generally, the organic amines, alkali–metal ions and saturated metal complexes are preferable to direct the formation of various vanadium borophosphate clusters, such as [VO(PO 3 OH) 5 B 2 O] 4− , 22 [VO(PO 3 OH) 4 (B 3 O 3 OH)] 4− , 27 [V 3 P 3 BO 19 ] 5− , 34,35 [(V 2 BP 2 O 12 ) 4 ] 12− , 29 [Na⊃(V 2 BP 2 O 12 ) 5 ] 14− , 29,30 and [A⊃(V 2 BP 2 O 12 ) 6 ] 17− (A = NH 4 + , K + , Rb + , Cs + ).…”
