Solution

CrCl3(py)3

IUPAC name: Trichloridotripyridinechromium (III)

Oxidation state of chromium = +3

Electronic configuration for d3 = t2g3

Coordination number = 6

Shape: octahedral.

Stereochemistry:

Both isomers are optically active. Therefore, a total of 4 isomers exist.

Magnetic moment, μ = `sqrt(n(n+2))`

`=sqrt(3(3+2))`

`=sqrt(15)`

`∼ 4BM`
