Twelve solid complexes of rare earth perchlorate with bis(benzoylmethyl) sulfoxide (L) and twelve-different proportional mixed complexes (Tb~(3+) mixed by Tm~(3+), Eu~(3+) mixed by Pr~(3+)) of rare earth perchlorate with the ligand (L) have been synthesized and characterized.

The solid complex of light rare earth samarium perchlorate with bis(benzoylmethyl) sulfoxide(L) has been synthesized and characterized by molar conductivity,elemental analysis and coordination titration.

Five solid complexes of proportional mixed complexes(Tb~(3+) mixed by Tm~(3+)) of rare earth perchlorate with the methyl-phenacyl sulfoxide have been synthesized.

Five different proportional binuclear complexes (mided Eu~(3+) and Tm~(3+)) of rare earth perchlorate with phenyl-phenacyl sulfoxide were synthesized.

Two complexes of alkaline-earth metals perchlorate with phenyl-acetylmethylene sulfoxide(C6H5SOCH2 COCH3) have been synthesized and characterized by elemental analysis and IR spectra.
