Simple transformations of an unbranched parent chain lead to a diverse range of aluminophosphates with 1D chain, 2D porous layer, and 3D open‐framework structures. A section of this chain, which has been hydrolyzed in one position leading to ring‐opening, is shown schematically below. Reorientation of the chain followed by renewed condensation leads to, for example, two edge‐sharing four‐rings. In this case water acts as a catalyst; thus the amount of water present during the synthesis determines the degree of hydrolysis and therefore the resulting structure type.
