Are we plotting molar susceptibility with variable temperature in VSM?

From this can we can obtain the mag.moment of any complexes and then we predict whether it is ferro or anti-ferro mag. Nature any papers or references since there is confusion that some one using...

I have an doubt since I used precursors for the preparation of complexes.

The excess precursor will regenerate as crystal or solvent recrystallise in the complex this question is relevant to previous question kindly give the suggestions

In VSM spectral studies of a dinuclear copper can be exist in the mag.moment of 2.26BM or not?

Because the mag,susceptibility or magnetic moment of mono nuclear copper in complexes seems to be 1.73 that means in dinuclear it should be 3.46 but its not what may be the reason any suggestions
