Poly(1,3,4-oxadiazoles) via aromatic nucleophilic displacement [PDF]
, 1992 Poly(1,3,4-oxadiazoles) (POX) are prepared by the aromatic nucleophilic displacement reaction of di(hydroxyphenyl) 1,3,4-oxadiazole monomers with activated aromatic dihalides or activated aromatic dinitro compounds. The polymerizations are carried out in

4-[4-(4-Amino-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazol-3-yl]-1,2,5-oxadiazol-3-amine [PDF]
Acta Crystallographica Section E Structure Reports Online, 2012 The complete molecule of the compound, C(6)H(4)N(8)O(3), is generated by a crystallographic twofold rotation axis that runs through the central ring. The flanking ring is twisted by 20.2 (1)° with respect to the central ring. One of the amino H atoms forms an intra-molecular N-H⋯N hydrogen bond; adjacent mol-ecules are linked by N-H⋯N hydrogen bonds ...
