Just to (possibly) clarify #2: the "models" will be the ones to move  
in the roll while any others remain fixed.  If you want any part to  
move relative to another, they must be in different models.  Even  
though the "axis" would contain the metal and one coordinating atom,  
"models" wouldn't necessarily have to include the metal.  Also, I  
don't think it is necessary to give the "center" in this case, because  
by default it will lie on the axis.
