Tricapped trigonal prismatic molecular geometry
molecular geometry
In chemistry, the tricapped trigonal prismatic molecular geometry describes one possible shape of compounds where nine atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a triaugmented triangular prism (a trigonal prism with an extra atom attached to each of its three rectangular faces).
It is very similar to the capped square antiprismatic molecular geometry, and there is some dispute over the specific geometry exhibited by certain molecules. For example, lanthanoid nine-coordinate 3+ complexes do not have a rigidly defined molecular geometry, meaning their assignment to a singular molecular geometry is problematic.
The public source identifies “Tricapped trigonal prismatic molecular geometry” as molecular geometry. This brief keeps that definition visible, then builds a research path around Tricapped, trigonal and prismatic.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Tricapped trigonal prismatic molecular geometry”, the useful work is to connect “molecular geometry” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q7840583. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
