文摘

A series of oligothiophene dinitriles, containing one, two, or three oligothiophene rings between nitrile donors NC-(C₄H₂S)_n-CN are reacted with silver(I) salts to form coordination compounds. In most cases, the resulting metal鈥搊rganic frameworks are one-dimensional coordination polymers containing roughly linear divalent Ag(I) centers. However, in the case of bithiophene (n = 2) and terthiophene (n = 3) bridges, a three-dimensional structure is also possible if the silver(I) counterion is just the right size to fit into the diamondoid pores that form with four-coordinate tetrahedrally oriented Ag(I) centers. Thus, only ClO₄^{鈥?/sup> and BF₄鈥?/sup> form three-dimensional structures with the bithiophene-bridged ligands, while the larger CF₃SO₃鈥?/sup> and SbF₆鈥?/sup> anions will support a three-dimensional structure for the terthiophene-bridged ligand. Any counterion larger or smaller than the 鈥渏ust right鈥?size will result in the one-dimensional structure instead.}
