Abstract
Nonpolar, organic solvent-soluble tellurium compounds and complexes are disclosed. The compounds are tellurium(II) compounds and are represented by the formula: Te[ (CH.sub.2).sub.n SiRR'R"].sub.2 wherein: n is an integer from 1 to 10 and R, R' and R" are independently selected from the group consisting of alkyl, aryl and heterocyclic radicals. Photosensitive complexes of these compounds with transition metals, as well as photographic elements having layers comprising these complexes, are also disclosed.

A tellurium(II) compound represented by the formula:
- Te[(CH.sub.2).sub.n SiRR'R"].sub.2
- wherein:
- n is an integer from 1 to 10 and
- R, R' and R" are independently selected from the group consisting of alkyl, aryl and heterocyclic radicals.
A tellurium(II) compound selected from the group consisting of:
- Te--CH.sub.2 Si(CH.sub.3).sub.3 ].sub.2,
- Te--CH.sub.2 CH.sub.2 CH.sub.2 Si(CH.sub.3)].sub.2
- and
- Te--CH.sub.2 Si(CH.sub.3).sub.2 C.sub.6 H.sub.5 ].sub.2.
A method of making a tellurium(II) compound represented by the formula:
- Te--(CH.sub.2).sub.n SiRR'R"].sub.2
- wherein:
- n is an integer from 1 to 10 and
- R, R' and R" are independently selected from the group consisting of alkyl, aryl and heterocyclic radicals, said method comprising the steps of:
- (a) reducing elemental tellurium to tellurium (2-) with a reducing agent and
- (b) reacting said tellurium (2-) with silicon-containing alkyl halide,
- wherein said steps are carried out in an inert atmosphere.
