MERLIN SCIENCE — No Primary Crystallographic Data Found for Posner Molecule Ca₉(PO₄)₆ — E8 Intelligence Research

Here is the finding. A search for primary crystallographic data on the Posner molecule, Ca₉(PO₄)₆, returned nothing but pedagogical symmetry tutorials. No lattice parameters, no space group determination, no bond lengths. Just teaching material about how point groups work. Let me put that in context for you. The Posner cluster is a nine-calcium cage wrapped around six phosphate groups. It shows up in bone mineralization, in calcium phosphate chemistry, and more recently in quantum-biology discussions about nuclear spin coherence. It is a real structure with real literature. And yet a general search surfaced only classroom content on Schoenflies notation, octahedral symmetry elements, and the icosahedral group of C60. Here is the reasoning you can evaluate. The search framing asserts the cluster has S₆ point symmetry. Let me be precise about what that means. S₆ is the cyclic group C₆i, order six, with elements E, C₃, C₃ squared, inversion, S₆, and S₆ to the fifth. It contains an inver Author: Andrew Stewart Caldin, Independent Researcher, UK.
