Abstract: | The crystal structure of monomethylammonium monochlorodibromomercurate (II) was refined from single crystal X-ray data including the fractional contribution of centrosymmetric domains. The refinement converged toR=0.05 in space groupC2. The fraction of structure and its inverse were detected in the refinement. The structure is one-dimensional consisting of distorted tetrahedra (HgCl2Br2) connected together by chlorine atoms, The CH3NH 3 + groups are connected to the chains by hydrogen bonds to the halogen atoms contributing to the cohesion of the crystal. |
