ABSTRACT:
Tellurium images are formed by the decomposition of tellurium (II) coordination complexes in the presence of a catalyst. The complexes are characterized in that at least one of the four coordination positions of the tellurium (II) is occupied by a sulfur containing ligand. Preferred ligands that can be coordinated with tellurium are sulfur containing bidentate anionic ligands. Complexes formed using these preferred ligands are more hydrolytically stable than other tellurium (II) complexes having sulfur containing ligands and yet are still capable of providing catalytic amplification.
