Tetrahedral framework structures with topologies that show close relationships to the feldspar group or to gismondine are formed by the zincoborophosphates A[ZnBP 2 O 8 ] (see picture). The compounds are readily accessible under mild hydrothermal conditions ( T max =170°C) and are thermally remarkably stable (for example, 940°C for A=Cs). Metalloborophosphates are a new class of compounds, which are expected to provide access to zeolite‐like microporous systems.
