Notes for the CIE O Level Chemistry – 25: Transition Elements. Transition Elements - Ligands and Complexes (1) Co-ordination numbers and structures : The co-ordination number for a metal ion in a complex is the number of ligand lone pairs that are attached to it.. For A level only co-ordination numbers of 4 and 6 are required, though co-ordination numbers can range up to 12 and beyond. Example: Let's consider the chemistry of cobalt which forms complexes that contain either Co 2+ or Co 3+ ions.
