Structural complexity in indium selenides prepared using bicyclic amines as structure-directing agents

5 January, 2015 - 16:17

Dalton Trans., 2015, 44,1592-1600
DOI: 10.1039/C4DT02819H, PaperS. J. Ewing, P. Vaqueiro
The use of bicyclic amines as structure-directing agents has resulted in the preparation of materials containing complex indium selenide ribbons (1-3), which can be linked into three-dimensional structures by unusual sodium complexes (4). Decomposition of the structure-directing agent leads to the formation of the dense three-dimensional framework found in 5.
