Total number of isomers of a compound having molecular formula, $K_{3} Fe (C_{6} N_{6})$ is :

Options:

Answer:

Solution:

The complex is $K_{3} [Fe (CN)_{6}]$ . The coordination number is 6, and the ligands are all identical (CN⁻). This complex is octahedral. Since all ligands are identical, there are no geometric isomers (cis/trans or facial/meridional). Also, there are no optical isomers because the complex is symmetrical. Therefore, only one isomer exists.

The correct answer is D.
