Abstract
The refinement of the structure of InSn2Br5 and InSn2I5 is reported. Both compounds crystallize with the tetragonal NH4Pb2Br5 type arrangement (a = 828.5(9) and 881.0(8) (pm), c = 1443.8(20) and 1524.0(3) (pm) respectively). We discuss the parameters in comparison with those of Tl5Se2I crystallizing in the antitype structure, and we derive the parameters of a model structure based on the packing of hard spheres. It can be shown, that bond distances and thermal parameters seeming unusual at first sight are not to be attributed to the interaction of lone pairs, since we find them in our model structure as well.Keywords
