Question #228658
The coordination number of the transition element in [PtClNO2(NH3)4]2- is?
Expert's answer
The transition element is Pt (platinum) in this formula. The coordination number of it is defined by the number of ligands, bounded with this element. Ligands can be atoms, ions and simple molecules. There are 6 ligands bounded with Pt in this formula: Cl, NO2 and 4 ions of NH3. So the coordination number of Pt is 6.
