Sažetak

The structures of the organomercury compounds have been
reviewed from the point of view of the secondary bonds which
mercury atom forms with the surrounding atoms. These bonds,
though rather labile, exhibit a definite influence on the crystal
structure which is manifested in a peculiar coordination around
the mercury atom. This influence has to be studied systematically
since the mercury coordination polyhedra in the crystal structure
of organomercury compounds are far from being regular. The
review has been restricted to the structures in which the secondary
bonds of mercury are shorter than the sum of the van der Waals
radii. The upper limit of the distances within the coordination
polyhedron cannot be well substantiated while the distances larger
than the sum of the van der Waals radii may be also influencial
in the structure. The influence of the long-range contacts, both on
the molecular structure as a whole as well as on the stability of
the secondary bonds, may be quite essential. The long-range contacts
actually reproduce the solvation effect in chemical reactions
in solutions. From this point of view the X-ray diffraction data
are useful for the study of the chemical reaction mechanism in
the organic chemistry of mercury.
