Pyramidin

Pyramidin is a fictional mineral term used in theoretical discussions and science fiction to describe a crystalline material built from pyramidal coordination units. It is not recognized as a real mineral or compound by major scientific catalogs or databases.

In the imagined models, pyramidin forms a three-dimensional network in which pyramidal or tetrahedral units share vertices to create a repeating lattice. Descriptions vary, with proposed symmetries including cubic, tetragonal, or orthorhombic, and with a framework that may include channels or voids.

Etymology and scope: The name combines “pyramid” with the common chemical suffix “-in,” a convention used in fictional compound naming. Pyramidin is typically treated as a generic class rather than a specific chemical formula in educational or narrative contexts.

Synthesis and occurrence: No real synthesis or natural occurrence is known. In fiction or thought experiments, pyramidin may be described as arising under hypothetical high-energy conditions or extraterrestrial environments, or used as a pedagogical device to discuss crystallography and material topology.

Notes and see also: See pyramid geometry, polyhedral chemistry, hypothetical materials. References to pyramidin appear in educational simulations and speculative fiction rather than in peer-reviewed scientific literature.
