It is proposed that a weighted coordination number, Z*, be used as a measure of the number of neighbours of an atom in a crystal. Coordinating atoms contribute faces to the Voronoi polyhedron around a central atom and their contributions are weighted in proportion to the solid angle subtended by that face at the centre. The advantages of this definition over other proposals are pointed out.
