| This poster will summarize the new results in the area of the formation of metal clusters using polynitrile building blocks. Molecular-assembly research often uses simple building blocks and connectivity principles to construct diverse new materials. We have used polynitrile angular linkers to chelate silver in a variety of complexes. Recently, we have used polycynaovinylarenes as building blocks, which were complexed with silver salts and their structures were determined using single-crystal X-ray diffraction. The molecular assembly of 9-(dicyanovinyl)anthracene (1) with silver hexafluoroantimonate from toluene resulted in a columnar structure. Complexation of 1 with silver hexafluoroantimonate from benzene resulted in a layered 3D network. In our more recent work, a Knoevenagel condensation with isophthalaldehyde and malononitrile yielded 1,3-bis(dicyanovinyl)benzene (4). Synthesis of 4 has produced a new pathway for the complexation of silver salts of compounds with numerous nitrile sites. These results will be presented in this poster. |
