| Abstract: | Reactions of NH2(CH2)
n
NH2 (n = 8,10) with elemental Sn and Se in a H2O/CH3OH mixture at 150°C afford two compounds (NH3(CH2)8NH3)Sn3Se7 (1) and (NH3(CH2)8NH3)Sn3Se7 (2). The crystal structures were determined by single crystal X-ray diffraction at room temperature. Both compounds exhibit the same anionic structure—a 63 netted plane composed of Sn3Se7]2– subunits. The distance between the centers of crystal 1 layers is 7.5 Å, somewhat shorter than the distance (8.5 Å) in crystal 2. |
