The Cl - Co - Cl bond angle values in a fac- Co NH 3 3 Cl 3 complex is/are:

Step-by-step solution

In facial isomer, three Cl atoms present on one face of the octahedron. Similarly, three ammonia molecules are present on one face of the octahedron. All 3 same ligands have 90 ° bond angle between them. The Cl - Co - Cl bond angle in above octahedral complex is 90 °
