• Bipyramid - Wikipedia

    en.wikipedia.org/wiki/Bipyramid An n-gonal bipyramid or dipyramid is a polyhedron formed by joining an n-gonal pyramid and its mirror image base-to-base. An n-gonal bipyramid has 2n triangle faces, 3n edges, and 2 + n vertices.. The referenced n-gon in the name of the bipyramids is not an external face but an internal one, existing on the primary symmetry plane which connects the two pyramid halves.

    medical-dictionary.thefreedictionary.com/bipyramidal The newly synthesized low-dimensional network is unique in the sense that the potassium metal ion is forming seven bonds through coordination with the four sulfide ions of thiol moieties of four different thiadiazole rings, one bond with nitrogen atom of azine nitrogens and two bonds with oxygen atoms of two hydroxyl ions observing a distorted pentagonal bipyramidal geometry.
  • Dipyramid -- from Wolfram MathWorld

    mathworld.wolfram.com/Dipyramid.html A dipyramid, also called a bipyramid, consists of two pyramids symmetrically placed base-to-base. The dipyramids are duals of the regular prisms. Their skeletons are the dipyramidal graphs. The volume of a dipyramid of half-height h and base area A_b is equal to twice the volume of the corresponding pyramid, namely V=2/3A_bh. (1) The volume of a dipyramid whose base is a regular n-sided ...
  • Triangular bipyramid - Wikipedia

    en.wikipedia.org/wiki/Triangular_dipyramid In geometry, the triangular bipyramid (or dipyramid) is a type of hexahedron, being the first in the infinite set of face-transitive bipyramids. It is the dual of the triangular prism with 6 isosceles triangle faces.. As the name suggests, it can be constructed by joining two tetrahedra along one face. Although all its faces are congruent and the solid is face-transitive, it is not a Platonic ...
  • Trigonal Bipyramid Molecular Geometry - Elmhurst College

    chemistry.elmhurst.edu/vchembook/220trigbipy.html An example of trigonal bipyramid molecular geometry that results from five electron pair geometry is PCl 5. The phosphorus has 5 valence electrons and thus needs 3 more electrons to complete its octet. However this is an example where five chlorine atoms present and the octet is expanded.
