| Abstract: | Crystal Growth and Refinement of the Crystal Structure of Mercury(II) Amide Chloride – HgClNH2 Single crystals were prepared by recrystallization of HgClNH2 from aqueous NH3/NH4+ solution at 160 °C. They were used for a single‐crystal X‐ray structure redetermination. The previously reported W. N. Lipscomb, Acta. Crystallogr. 1951 , 4, 266.] structural topology determined on basis of X‐ray powder diffraction data is now confirmed. However, a higher symmetry is found: Space group type Pmma (instead of Pmm2), a = 6.709(1) Å, b = 4.351(1) Å, c = 5.154(1) Å, Z = 2. The crystal structure contains zig‐zag‐chains Hg(NH2)2/2]+. Four Cl atoms complete the coordination sphere of Hg to a distorted octahedron. These share common faces and edges in layers HgCl4/4(NH2)2/2]. These layers are connected via hydrogen bonds N–H…Cl. |
