Fosforhape

Fosforhape is a term used in speculative chemistry and some fictional settings to describe a proposed class of phosphorus-centered molecular geometries and the corresponding observed or anticipated shapes of materials built from phosphorus-containing units. The word blends "phosphorus" and "shape" and is not part of the standard nomenclature of inorganic chemistry.

In the imagined framework, fosforhape encompasses a range of phosphorus coordination environments, from low-coordinate, pyramidal P(III) centers to higher-coordinate or hypervalent P(V) arrangements, where the ligands and substituents bias the angles to produce characteristic three-dimensional motifs. Proponents use the concept to discuss how changes in oxidation state, ligand identity, or assembly conditions might drive predictable shape changes in molecules and in extended networks.

Characterization in theoretical or fictional use relies on computational geometry, simulated diffraction patterns, and spectroscopic fingerprints; in real chemistry, similar discussions are addressed with established terms for molecular geometry, such as bond angles around phosphorus and the classification of phosphorus compounds by symmetry.

Examples cited in speculative literature include hypothetical organophosphorus polymers or coordination frameworks where the arrangement of phosphorus centers yields reversible shape transformations. No experimentally verified class named fosforhape exists in mainstream chemical databases as of now, and the term remains informal.

Despite its uncertain status, the concept reflects ongoing interest in how phosphorus-centered frameworks can control geometry and material properties, a theme that appears in real phosphorus chemistry under headings such as molecular geometry, polyphosphorus compounds, and organophosphorus materials.
