Generally, the coordination number and the nature of the electronic absorption band ( $\mathrm{f} \rightarrow \mathrm{f}$ transition )of lanthanide (III) ion in their complexes are respectively
(a)greater than 6 and sharp
(b)6 and broad
(c)less than 6 and sharp
(d)greater than 6 and broad
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Ln(III) ions favour coordination numbers > 6, and their shielded f–f transitions are sharp, weak lines (a).
