Title in Portuguese
Determinação estrutural e estudo da estereoespecificidade de compostos de paládio II
Keywords in Portuguese
Estereoespecificidade
Paládio II

Abstract in Portuguese
Neste trabalho estão apresentadas as estruturas cristalinas e moleculares e o estudo da estereoespecificidade de compostos de paládio com geometria de coordenação quadrado planar. Estas estruturas foram determinadas com o objetivo de verificar a relação entre a geometria e sua potencialidade como um possível agente anti-cancerígeno.
No estudo de correlação através de Quimiometria foi introduzida como parâmetros a distância do átomo de paládio ao plano, que avalia o quanto o átomo de paládio esta distante do plano formado pelos seus quatro ligantes, o ângulo de ligação, onde se observa a distorção dos ângulos entre os átomos coordenados ao paládio e a superfície de van der Waals calculada para a molécula.
O estudo da relação destes parâmetros mostrou que eles são suficientes para realizar a separação entre ativos e inativos, indicando para os inéditos, com estrutura estudada neste trabalho, a possível (ou não) atividade.

Abstract in English
This work presents the crystal and molecular structures and the study of stereospecificity of palladium compounds with square planar coordination geometry. These structures were determined with the objective of verifying the relationship between the molecular geometry and its potential as a possible anti-tumor agent.
In the correlation study by Chemometry, the parameters introduced were: the distance from the palladium atom to the plane, which assesses how much the palladium atom is far from the plane formed by its four ligands, the bond angle, that shows a noticeable distortion of the angles between the atoms coordinated to the palladium atom, and van der Waals surface calculated for the molecule.
The relationship between these parameters showed that they are sufficient to accomplish the separation between active and inactive molecules, indicating for the novel, with structure studied in this work, the possible (or not) activity.
