These values are quite large and unusual for copper complexes, are you sure you have no error in frequency determination or did you use any standard for g determination?

Oleg is correct. D9 complexes tend to have one g value very close to 2. Either you have a calibration error, easily detected by running a weak pitch error, or you have something more interesting than a simple copper complex, perhaps a spin coupled multimer,

Dear Wael Khalil El- Tramsey,

Above two is ok normal only acceptable. But below two is not acceptable ok. I thing your value is acceptable ok.

Mr. El- Tramsey,

You have rather compressed octahedron, which for CuII-complexes is very unusual. It would be interesting to confirm this by independent method. A correlation with magnetochemical data would be very valuable.

Please pay attention to papers below, where there is found elongated Oh geometry for CuIIX4Y2 chromophores.
