Bromido(2,4,6-trimethylphenyl)mercury(II)

Abstract

Mol­ecules of the title compound, [HgBr(C9H11)], are located on a crystallographic twofold rotation axis. Due to the mol­ecular symmetry, the HgII atom is linearly coordinated by the ipso-C of the mesityl group and the Br atom. In the crystal, mol­ecules lie in planes parallel to (001).

1-(Bromomercurio)ferrocene

“…Two molecules A and two molecules B are connected by four additional Hg···Br contacts to form eight-membered (HgBr) 4 rings. No intermolecular Hg···Br contacts occur in the crystal structure of 1-(bromomercurio)-2,4,6-trimethylbenzene (Meyer-Wegner et al, 2012). There an undistorted HgBr single bond length of 2.4307 (8) Å was found which is about 0.02 Å shorter than the values of 2.4511 (9) and 2.4562 (7) Å observed for molecules A and B of the title compound.…”

“…Our group has recently reported on the chemical and structural features of compounds containing the group 12 elements Zn, Cd and Hg (Meyer-Wegner et al, 2012;Hayashi et al, 2011;Franz et al, 2011;Lerner, 2005;Wiberg et al, 1997;Wiberg et al, 2001;Margraf et al, 2004). To extend our long-standing investigations in this field, we are currently studying the title compound 1-(bromomercurio)ferrocene.…”
