From this study it can be concluded that: (i) the average distribution of atoms gives a cubic unit cell for both compounds though the study is conducted at a temperature close to Tc for PST, and lower than Tc for PSN; (ii) PST and PSN present the classical {111}-type ordering and PST material has always a higher degree of ordering than PSN when they are prepared under similar conditions; (iii) small domains of {110}-type ordering are observed in these two compounds leading to supplementary reflections, even by X-r ay diffraction in the case of PSN. Abstractde Une étude comparative des pérovskites Pb2ScTaO6 et Pb2ScNbO6 non recuites et obtenues dans des conditions semblables a été réalisée à température ambiante par diffraction de rayons X et d'électrons, ainsi que par MEHR. D'après cette étude nous pouvons déduire que: (i) La distribution atomique moyenne conduit à un réseau cristallin de maille cubique pour les deux composés, bien que l'étude soit réalisée à une température proche de Tc pour PST et inférieure à Tc pour PSN. (ii) PST et PSN présentent un ordre de type {111}, mais le degré d'ordre pour PST est toujours supérieur à celui de PSN (PST et PSN étant préparés dans les měmes conditions). (iii) De petits domaines d'ordre de type {110} apparaissent dans ces deux composés conduisant à des réflexions supplémentaires, observées měme par diffraction de rayons X dans le cas de PSN.
