Tetrameric dichloro(trimethylammonio-p-toluenesulfonamidate)-mercury(II)

In the title compound, hexa-mu-chloro-dichlorotetrakis(Ntrimethylammonio-p-toluenesulfonamidate -kappa(2)N,O)tetramer- cury(II), [Hg{Me3N(+)N(-)SO2C6H4CH3-p}Cl-2](4) or [Hg4Cl8(C10H16N2O2S)(4)], four nearly linear and parallel Cl-Hg-Cl units associate through pairwise Hg…Cl interactions of 3.1-3.2Angstrom. Each Hg atom is also coordinated through N and O atoms to a ylide molecule. The available structural data indicate that coordination of a sulfonyl-stabilized nitrogen ylide to a metal atom (Hg or Ag) has no detectable effect on its geometry.
