Answer
$CrCl_3(py)_3$
IUPAC name: Trichloridotripyridinechromium (III).
Oxidation state of chromium = $+3$
Electronic configuration for $d^3 = t_{2g}^3$
Coordination number = $6$
Shape: octahedral.
Stereochemistry:
Both isomers are optically active. Therefore, a total of 4 isomers exist.
Magnetic moment, µ$=\sqrt{\text{n}(\text{n}+2)}$
$=\sqrt{3(3+2)}$
$=\sqrt{15}$
$=∼4\text{BM}$
