Prismatoid polyhedra

Pentagrammic cuploid

In geometry, the pentagrammic cuploid or pentagrammmic semicupola is the simplest of the infinite family of cuploids. It can be obtained as a slice of the small complex rhombicosidodecahedron. As in all cupolae, the base polygon has twice as many edges and vertices as the top; but in this case the base polygon is a degenerate {10/2} decagram, as the top is a {5/2} pentagram. Hence, the degenerate base is withdrawn and the triangles are connected to the squares instead. (Wikipedia).

Introduction to Inorganic and Organometallic Chemistry

So far we've learned a lot about general chemistry and organic chemistry, so let's move into inorganic chemistry and organometallic chemistry. In this series we will investigate all the elements on the periodic table that were ignored in organic chemistry, especially the transition metals.
