Trigonal bipyramidal

Trigonal bipyramidal is a molecular shape where five atoms or groups are arranged around a central atom. Imagine a pyramid with a triangle base: three atoms sit at the corners of the triangle (equatorial positions), and two atoms are placed above and below the center (axial positions). This arrangement results in bond angles of 120 degrees between the equatorial atoms and 90 degrees between the axial and equatorial atoms, creating a symmetrical, five-sided structure. It describes molecules where atoms are spaced as evenly as possible around a core atom, often seen in certain chemical compounds.
