The cis form of the complex `[RhCl_(3)(py)_(3)]` is called …… isomer whereas its trans form is called …… isomer.

Explanation

To solve the question regarding the cis and trans forms of the complex \([RhCl_3(py)_3]\), we need to identify the names of these isomers based on their geometric configurations.

### Step-by-Step Solution:

1. **Identify the Complex**: The complex given is \([RhCl_3(py)_3]\). Here, Rh is the central metal atom (rhodium), Cl is a ligand (chloride), and py represents pyridine, another ligand.

2. **Determine the Coordination Geometry**: The complex has a coordination number of 6 (3 chloride ligands and 3 pyridine ligands). This typically suggests an octahedral geometry.
