Common Features in the Crystal Structures of the Compounds Bis (dimethylstibanyl) oxane and??sulfane, and the Minerals Valentinite and Stibnite (Grauspießglanz)
Abstract Bis (dimethylstibanyl) oxane (1) and-sulfane (2), the two simplest organoelement species with an Sb–E–Sb fragment (E= O, S), were prepared by alkaline hydrolysis of bromodimethylstibane and by oxidation of tetramethyldistibane with sulfur [18], respectively. As shown by an x-ray structure analysis of compound 1 (mp<–20 C; P2 1 2 1 2 1, a= 675.9 (2), b= 803.1 (2), c= 1666.8 (4) pm at–70±2 C; Z= 4; R1= 0.042), the molecules (O–Sb ...
