Crystal Structure of Cesium Phenylacetylide, CsC₂C₆H₅, Solved and Refined from Synchrotron Powder Diffraction Data

Abstract

Abstract. The crystal structure of cesium phenylacetylide, CsC 2 C 6 H 5 , was solved and refined from synchrotron powder diffraction data (Pbca, Z = 8). Each Cs + cation is coordinated by five ligands: four acetylide groups coordinate side-on and one end-on. A similar arrangement is found in the crystal structure of NaC 2 H (P4/nmm, Z = 2). There is a group-subgroup relationship between both structures. Most
