The highly charged dodecaniobate Keggin ions [XNb12O40](-16) (X = Si, Ge) and [XNb12O40](-15) (X = P) serve as building blocks of self-assembled, low-dimensional anionic framework materials. In addition to its high charge, the Keggin ion provides opt

The recent expansion of zeolitic synthesis toward mixed geometry frameworks reflects their potential applications in shape-selective catalysis and absorption. Four scandium phosphates with three-dimensional frameworks have been hydrothermally synthes
