Resumé en portugais
Foram determinadas as estruturas de três complexos de Platina, dois complexos de estanho e um ligante orgânico. AS intensidades das reflexões foram medidas com umdifratômetro CAD-4. As estruturas foram resolvidas por métodos diretos ou pela função de Patterson e refinadas por mínimos quadrados. Bis (fenilsulfonil) etano, C14H14(SO2)2, foi obtido durante as tentativas de sintetizar ligantes para serem usados na complexação com diversos organo-estânicos, o cristal pertence ao sistema moniclínico, P21/n, a= 8,495(3), b= 10,159(1), c= 9,072(1)Å, β= 116,23(2) °, V= 702,3(3) Å3, Z= 2, dcalc= 1,467g.cm-3.

Resumé en anglais
The structures of three platinum complexes, two organotin compounds and organic ligand were determined. The reflection intensities were measured with a CAD-4 automatic diffractometer. The structures were solved by direct methods or the Patterson function and were refined by least squares method. Bis (phenylsulfonyl)ethane, C14H14(SO2)2, was obtained among attempts to synthesize ligands to be used for complexation with several organotins, the crystal belongs to the monoclinic system, P21/n, a= 8,495(3), b= 10,159(1), c= 9,072(1)Å, β= 116,23(2) °, V= 702,3(3) Å3, Z= 2, dcalc= 1,467g.cm-3. Cis-dichloro [ meso 1,2-bis(n-propylsulphinyl)ethane]platinum(II), PtCl2. (PrSO)2C2H4 the crystal belongs to the orthorhombic system, P212121, a= 7,360(2), b= 9,793(2), c= 19,369(2)Å, V= 1396,1(4)Å3, Z= 4, dcalc= 2,25g.cm-3.
