उत्तर
A coordination polyhedron is defined by the spatial arrangement of the ligand atoms that are directly connected to the centre atom or ion. For example:
- [Cu(NH3)4]2+: The coordination polyhedron of copper in this complex is a square planar geometry, as there are four ammonia ligands arranged in a square around the central copper ion (coordination number 4).
- [Fe(CN)6]4−: The coordination polyhedron of iron in this complex is octahedral, with six cyanide ligands arranged around the central iron ion (coordination number 6).
