Metal ion electron density

Hi all;

We have a protein that coordinates Ca2+.  The electron density is oblong
instead of spherical.  This is true in both the Fo-Fc without Ca2+ in the model
and in the 2Fo-Fc with Ca2+.

Does any one else see this non-spherical density phenomenom in a Ca2+ (or other
metal ion) coordinating a macromolecule?
