摘要
Reactions of NH2(CH2)(n)NH2 (n = 8, 10) with elemental Sn and Se in a H2O/CH3OH mixture at 150degreesC afford two compounds (NH3(CH2)(8)NH3)Sn3Se7 (1) and (NH3(CH2)(8)NH3)Sn3Se (2). The crystal structures were determined by single crystal X-ray diffraction at room temperature. Both compounds exhibit the same anionic structure-a 6(3) netted plane composed of [Sn3Se7](2-) subunits. The distance between the centers of crystal 1 layers is 7.5 Angstrom, somewhat shorter than the distance (8.5 Angstrom) in crystal 2.
