13 - 003Synthesis of Potassium Cyanamide, and Crystal Structure Deter-mination by Pareto Optimization of the Cost Functions ”LatticeEnergy” and ”Power Intensities”. — K2CN2 is prepared from KHCN2

and KNH2 in liquid NH3 at -50 ◦C. The crystal structure of the compound isrefined from powder XRD data. K2CN2 crystallizes in the monoclinic spacegroup C2/m, with Z = 2. The structure consists of linear CN2

2− anions andKN5/5 square pyramids which are connected via common edges forming layersrunning along the a/b-plane. — (BECKER, MICHAEL; JANSEN, MARTIN;Solid State Sci. 2 (2000) 7, 711-715; MPI Festkoerperforsch., D-70569 Stuttgart,Germany; EN)
