+**D5d** is a [point group](/wiki/point_group) in crystallographic and molecular symmetry. This class is defined by a five-fold principal rotation axis and perpendicular two-fold axes, implying a [staggered](/wiki/staggered) or antiprismatic arrangement often seen in specific [polyhedra](/wiki/polyhedron).
