Abstract: The crystal structures of four organoselenium compounds, viz. bis(2-formylphenyl)diselenide (5), bis(2 -methylnaphthyl)diselenide (6), organoselenenyl sulfide (7), and spiroselenurane (8) are described. Crystal data for 5: space group Pca2(1), crystal system orthorhombic, a = 7.9969(4) angstrom, b = 20.8794(12) angstrom, c = 15.8307(13) angstrom, Z = 8, R = 0.0292. Owing to the presence of a strong Se center dot center dot center dot O interaction in compound 5 the geometry around the selenium atom may be considered as T-shaped. Crystal data for 6: space group Pna2(1), crystal system orthorhombic, a = 18.2253(12) angstrom, b = 13.0714(8) angstrom, c = 7.7355(5) angstrom, Z = 4, R = 0.0570. The molecule has a cisoid conformation. Crystal data for 7: space group Pbcn, crystal system orthorhombic, a = 22.2144(13) angstrom, b = 8.0255(4) angstrom, c = 15.4496(9) angstrom, Z = 8, R = 0.0292. Due to intramolecular Se center dot center dot center dot N interaction in 7 the geometry around selenium is T-shaped. Crystal data for 8: space group P2(1)/c, crystal system monoclinic, a = 7.4585(5) angstrom, b = 19.5634(13) angstrom, c = 8.0428(5) angstrom, P = 97.1320(10)degrees, Z = 4, R = 0.0254. The O - Se - O angle is 172.86(6)degrees.
