 Hi Sergio,
ShaEP is a free-of-charge program that can superimpose molecular
 structures by maximizing their volume overlap. By default, it also
 takes
 into account the electrostatic potential of the molecules but that can
 be turned off. You can download ShaEP for Windows, Linux, Mac, or
 FreeBSD from
