Crystal structure of bis-(4-acetyl-anilinium) tetra-chlorido-mercurate(II).

ABSTRACT: The structure of the title salt, (C8H10NO)2[HgCl4], is isotypic with that of the cuprate(II) and cobaltate(II) analogues. The asymmetric unit contains one 4-acetyl-anilinium cation and one half of a tetra-chlorido-mercurate(II) anion (point group symmetry m). The Hg-Cl distances are in the range 2.4308?(7)-2.5244?(11)?Å and the Cl-Hg-Cl angles in the range of 104.66?(2)-122.94?(4)°, indicating a considerable distortion of the tetra-hedral anion. In the crystal, cations are linked by an inter-molecular N-H?O hydrogen-bonding inter-action, leading to a C(8) chain motif with the chains extending parallel to the b axis. There is also a ?-? stacking inter-action with a centroid-to-centroid distance of 3.735?(2)?Å between neighbouring benzene rings along this direction. The anions lie between the chains and inter-act with the cations through inter-molecular N-H?Cl hydrogen bonds, leading to the formation of a three-dimensional network structure.
