The structural aspects of the complexes formed by thiosemicarbazones (TSCs)
and semicarbazones (SCs) with the metallic elements of Groups 12, 13, 14 a
nd 15 are surveyed up to 1998. Descriptions of 71 structures containing neu
tral or deprotonated TSCs and ten with SCs include information on the metal
-to-ligand bonds and the coordination behaviour of the ligand. The survey s
hows that TSCs are very versatile coordination agents with these accepters.
