However it is also possible that there are 6 water molecules in the equatorial plane, hexagonal bipyramid, point group D 6h, as many complexes with this structure are known.
22.
The term "'dodecadeltahedron "'is sometimes used to distinguish the bipyramid from the Platonic solid, although in chemistry this term more often refers to the snub disphenoid.
23.
An important aspect of this project was based on the possibility of phosphorus ( IV ) to accommodate a fifth ligand under formation of a trigonal bipyramid which shows a number of unique properties.
24.
Rhenium is the only metal known to bond with seven fluorides, which is the record for number of charged ligands for a charge-neutral metal compound . Rhenium heptafluoride adopts a pentagonal bipyramid molecular geometry.
25.
This scheme takes advantage of the fact that the regular icosahedron is a pentagonal gyroelongated bipyramid, with D 5d dihedral symmetry that is, it is formed of two congruent pentagonal pyramids joined by a pentagonal antiprism.
26.
Its geometry is, in essence, a 7-boron framework ( pentagonal bipyramid ), missing a vertex that had the highest number of near neighbours, e . g ., a vertex with 5 neighbours.
27.
The dihedral symmetry D p has order " 4n ", represented the faces of a bipyramid, and on the sphere as an equator line on the longitude, and n equally-spaced lines of longitude.
28.
A second projection takes the " 2 ( n-1 ) "-gon petrie polygon of the lower dimension, seen as a bipyramid, projected down the axis, with 2 vertices mapped into the center.
29.
One construction which is certainly possible is as a bipyramid, composed of triangles ( the AD & D d10 is a ( distorted ) pentagonal bipyramid ) .-- talk ) 20 : 12, 12 October 2007 ( UTC)
