Résumé
Two adducts, 2Cu(en)(2)Cl-2 center dot 4SnPh(2)Cl(2 center dot)SnCl(4) and Cu(en)(3)CuCl4 SnPh3Cl have been synthesized, their infrared and Mossbauer studies carried out. The suggested structures are ionic and contain [SnPh2Cl3] involved in coordination to the Cu centres through Cl in the first adduct, while, in the second adduct, a coordinated SnPh3Cl molecule through the free N atom of [Cu(en)(3)](2+) is suggested. The environment around Cu2+ is octahedral, square pyramidal or tetrahedral, the tin(IV) centres having bipyramidal trigonal or tetrahedral environments.
