Abstract
Crystals of
acetato(methanethiolato)-γ-picolinemercury(11), MeSHgO2CMe,C6H7N
(I), are monoclinic, P21/a, a
16.617(9), b 7.271(3), c 20.476(2) � β 113.31(5)�, Z 8.
The structure resembles that of its pyridine analogue, being based on a
polymeric (-Hg-SMe-)n
chain with acetate and picoline groups coordinated at each mercury; a similar
structure is found for EtSHgO2CMe,C5H5N (2),
monoclinic, P21/c, a
9.344(2), b 17.917(9), c 7.179(2) �,β 106.24(3)�, Z 4.
The structure of tetrachlorotetra(2-methylpropane-2-thiolato)di(γ-picoline)
tetramercury(11), (BUtS)4Cl4Hg4(C6H7N)2
(3), also resembles that of its pyridine analogue being based on an unusual
tetranuclear grouping of mercury atoms linked by chloride and thiolate bridges.
Crystals of (3) are monoclinic, P21/c a 12.334(7), b 17.468(9),
c 9.999(5) �, β 91.18(4)�, Z 2.
Crystals of MeSHgBr (4) are monoclinic, P21/c, a 7.770(9), b 7.500(5), c 7.945(10) �, β 91.71(3)�, Z 4,
and contain parallel chains (-Hg-SMe-)n
with neighbouring chains linked by bridging bromine atoms into parallel sheets.
Each bromine is triply bridging, being coordinated to two mercury atoms in one
chain, and one mercury atom in an adjacent chain. The structure of MeSHgCl
appears to be isomorphous.
