Concept explainers
(a)
Interpretation: The formula for the given coordination complex needs to be determined.
- Hexakis(pyridine)cobalt(III) chloride
Concept Introduction: A coordination complex is composed of two main parts; metal atom/ ion and ligand. Ligands are the atom/ group of atom/ ion that can donate its extra pair of electrons to the electron deficient metal cation. It leads to the formation of coordinate bond between metal ion and ligand.
(a)
Answer to Problem 73AE
Explanation of Solution
In the formula of writing and naming of coordination complex; IUPAC rule must be followed.
- Atomic symbol of the metal center must be written first in the square bracket.
- Ligands must be written after metal symbol in sequence of anion then neutral ligand.
- The ligands must be written in alphabetical order.
- The number of ligands or metal must be indicated as sub-script.
- Counter ion must be written outside the square bracket.
In Hexakis(pyridine)cobalt(III) chloride; chloride ion is counter ion with
