In geometry, a polyhedral compound is a figure that is composed of several polyhedra sharing a common centre. They are the three-dimensional analogs of polygonal compounds such as the hexagram. The outer vertices of a compound can be connected to form a convex polyhedron called its convex hull. A compound is a facetting of its convex hull.

The term ‘coordination polyhedron’ describes ligands’ geometric pattern or spatial arrangement directly linked to the centre atom or an ion. The most frequent coordination polyhedra are tetrahedral, octahedral, and square planar geometries. For example: The geometry of [Ni(CO)4] is tetrahedral

One or more italicised letters indicate the geometry, e.g. TP-3 which is followed by a number that gives the coordination number of the central atom. The polyhedral symbol can be used in naming of compounds, in which case it is followed by the configuration index. shannon gowerWebIn chemistry the polyhedral skeletal electron pair theory (PSEPT) provides electron counting rules useful for predicting the structures of clusters such as borane and carborane … poly tube bunningsWeb2. The coordination geometry around the central atom corresponds to the polyhedron whose number of vertices is equal to the number of surrounding electron pairs (coordination number).
