Sodium propynoate, Na(O 2 CC,CH) 1, was synthesized from propynoic acid and sodium hydroxide in methanol solution. Irradiation of solid 1 with 60 Co -rays (654 kGy dose) leads to an amorphous dark-colored acetylenic polymer in high yield. An X-ray structure determination of compound 1 shows that the
A new cocrystalline salt, 5-bromo-2-aminopyridinium propynoate 7, has been synthesized. Inspection of the crystal structure reveals that the packing differs markedly from that of the chemically analogous species 2-aminopyridinium propynoate 1. While 1 undergoes a thermally-induced Michael addition r
1. In acetonitrile solution, 1 is monomeric. X-ray analysis shows that 1 forms an infinite, one-dimensional solid-state extended structure. Each copper ion is coordinated by three sulfur donors, two from one ligand and the third from a second ligand. The approximate tetrahedral coordination sphere i
