SiMe3}2]. The ionic complex [HgCl{Te(Ph)CH2SiMe3}3]Clꢀ2EtOH is
isolated by treating [HgCl2{Te(Ph)CH2SiMe3}2] with CH2Cl2 for a
short time followed by recrystallization from EtOH. The products
were characterized by X-ray crystallography as well as multinu-
clear NMR. The solid state lattices are formed by discrete molecular
species or ions, but with extensive HꢀꢀꢀCl hydrogen bonding net-
work. In case of 6b, significant secondary HgꢀꢀꢀCl bonding interac-
tions are also observed.

The formation of 6b can be explained by the equilibrium between
complexes 4 and 6 that show the same Hg:Cl:TeR2 molar ratio.
We also note that when 3a was dissolved in CH2Cl2, the 125Te

Furthermore, a resonance at 800 ppm was found in the spectrum.
This resonance is tentatively assigned to PhTeCl2CH2SiMe3 and
could be due to the reaction of the excess ligand with Clꢀ radicals
that are formed by the decomposition of CH2Cl2, since the reactions
were carried out in light.
