The present volume of the Gmelin thorium series describes the solid
thorium-carbon compounds with the exception of the carbides and
coordination compounds of the type 4 ThAn* X B, where B is a
neutral ligand. The complex equilibria of the Th + ion with
C-containing complexing agents are treated in the ThD1 volume. A
first look into this volume demonstrates that a very large number
of ThlV complexes has 4 been prepared. This may be explained by the
fact that the Th + ion is the largest tetravalent ion of the
periodic table. Therefore, the preparation of complexes with, e. g.
, multidentate ligands can give a well-established picture of the
coordination number as a function of charge and ionic radius.
However, there are very few modern and updated comprehensive
treatments of such data. Many compounds described in this volume
are characterized by no other means than analytical composition and
IR spectra (whereby IR spectra of organic ThlV salts mostly give
information only on the ligand). Besides thorium carbonate and
carbonato complexes, which are relevant for the environmental
behaviour of this radioactive element and some organic complexes
like oxalates, which are used in the field of analytical and
separation chemistry nearly all other compounds described here are
practically only of scientific interest. On the other hand in order
to have scientifically reliable data, a very large part of these
compounds needs further investigation and characterization.
