Abstract
The crystal structures of four organoselenium compounds viz bis2formylphenyldiselenide 5 bis2methylnaphthyldiselenide 6 organoselenenyl sulfide 7 and spiroselenurane 8 are described Crystal data for 5 space group Pca21 crystal system orthorhombic a=799694 Å b=20879412 Å c=15830713 Å Z=8 R=00292 Owing to the presence of a strong Se···O interaction in compound 5 the geometry around the selenium atom may be considered as Tshaped Crystal data for 6 space group Pna21 crystal system orthorhombic a=18225312 Å b=1307148 Å c=773555 Å Z=4 R=00570 The molecule has a cisoid conformation Crystal data for 7 space group Pbcn crystal system orthorhombic a=22214413 Å b=802554 Å c=1544969 Å Z=8 R=00292 Due to intramolecular Se···N interaction in 7 the geometry around selenium is T shaped Crystal data for 8 space group P21/c crystal system monoclinic a=745855 Å b=19563413 Å c=804285 Å β=97132010° Z=4 R=00254 The O−Se−O angle is 172866°
