Abstract

The article discusses the synthesis and characterization of a new compound, Na2C3O2, which contains an unusual Y-shaped −C≡C−COO− anion. The compound was obtained through a reaction using sodium electride or NaC2H and the sodium salt of propargyl acid in liquid ammonia. The structure of Na2C3O2 was determined using synchrotron powder diffraction data and confirmed through spectroscopic analysis. The compound exhibits coordination of the anion to the sodium cation through both its carboxylate group and its negatively charged acetylide unit. The article provides detailed information on the synthesis, structure, and spectroscopic characterization of Na2C3O2. The authors acknowledge the assistance of various individuals and organizations in conducting the research. This report, authored by Sebastian, Renée Siegel, Jürgen Senker, Jan Hempelmann, Richard Dronskowski, and Uwe Ruschewitz, provides valuable insights into a specific topic.
