Question

Quizplus · Accepted Answer

The coordination number is the number of ligands attached to the central metal ion. In this case, there are 6 ligands - two en (ethylene-diamine) molecules, one chloride ion, and three sulfur atoms (from B14S1U1 and B0 ligands). Therefore, the coordination number of cobalt in the complex ion [Co(en)Cl₄]¯ is 6.
