For transition metal complex, from its magnetic susceptibility, How to calculate effective magnetic moment ( (μf , in unit of Bohr magneton ) and can i predict the number of unpaired electrons and structure geometry .
You can calculate magnetic moment and also you will come to know (read what is spin-orbit coupling and its influence on magnetic properties), if there is any spin-orbital coupling besides comparing spin-only values and hence its splitting and the geometry as well. However, by looking into the composition and the nature of the ligands and the metal salt used in the complexation reaction, you must be having some idea. Now you can confirm the structural features. For magnetic susceptibility (molar or volume) and Bohr magneton relationship, already some one had given the equation. Now your job has become easy. For these things try to find out yourself instead of asking others to do your job. In that process you will not learn much.

Hi Maravanji,
You can determine the magnetic susceptibility and moment values based on Evans' methods in solution (pls. see the references: Monatsh. Chem., 125, 661-670 (1994) ; Bull. Chem. Soc. Jpn.,75, 2449-2453 (2002); , J. Coord. Chem., 42, 231-239 (1997); Inorg. Chem., 57:21, 13397-13408 (2018).
Yes, you can predict the spin-state (no.of unpaired electrons) as well as the geometry of the complexes.
