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

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.

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

The structure of the title salt, (C8H10NO)2[CoCl4], is isotypic with the analogous cuprate(II) structure. The asymmetric unit contains one 4-acetyl-anilinium cation and one half of a tetra-chlorido-cobaltate(II) anion for which the Co(II) atom and two Cl(-) ligands lie on a mirror plane. The Co-Cl distances in the distorted tetra-hedral anion range from 2.
