Pentagonal bipyramid

<p>The pentagonal bipyramid (or pentagonal dipyramid) is a polyhedron with ten triangular faces. It is constructed by attaching two <a href="/facts/Pentagonal_pyramid/tN5CBPjK">pentagonal pyramids</a> to each of their bases. If the triangular faces are <a href="/facts/Equilateral_triangles/MJomsYDS">equilateral</a>, the pentagonal bipyramid is an example of <a href="/facts/Deltahedra/qDjkasx9">deltahedra</a>, <a href="/facts/Composite_polyhedron/z1pUdj7r">composite polyhedron</a>, and <a href="/facts/Johnson_solid/8SR7CyNz">Johnson solid</a>.

This polyhedron may be used in the <a href="/facts/Chemical_compound/37FXqqtv">chemical compound</a> as the description of an <a href="/facts/Atom_cluster/EsuLgxJU">atom cluster</a> known as <a href="/facts/Pentagonal_bipyramidal_molecular_geometry/tQ4fA46l">pentagonal bipyramidal molecular geometry</a>, as a solution in <a href="/facts/Thomson_problem/eyDlFwy4">Thomson problem</a>, as well as in <a href="/facts/Decahedral_nanoparticle/kkIwuR77">decahedral nanoparticles</a>.
