Trimethylphenylammonium trichloromercurate(II), (Me3PhN)[HgCl3]

P. Nockemann and G. Meyer

Abstract: The crystal structure of (Me3PhN)[HgCl3] contains [(CH3)3(C6H5)N]+ cations and chains of distorted vertex-sharing [HgCl4]2- tetrahedra running parallel to [100]. The tetrahedra around mercury(II) are distorted, exhibiting a [2+2] coordination. Apart from one of the Cl atoms, which is located on a twofold rotation axis, and a pair of symmetry-related methyl C atoms, which are located in general positions, all non H-atoms lie on mirror planes.
