INORGANIC MACROMOLECULES CONTAINING A SILICON-OXYGEN-METAL LINKAGE.

Abstract

The general purposes of the investigation were (1) to develop techniques for preparing compounds containing the silicon-oxygen-metal linkage, (2) to study and enhance the stability of this linkage to chemical and thermal degrad ation, and (3) to build inorganic polymers containing a silicon-oxygen-metal backbone which would behave as elastomers at temperatures in the range 300-600C. Compounds were prepared containing the linkage Si-O-M where M is vanadium, niobium and tantalum, chromium and tungsten, phosphorus and tin. In addition, and as a direct outgrowth of attempts to stabilize the linkage by coordinatively saturating the metal, two new, true tetramolybdates were characterized and the coordinating tendencies of the blocking ligand P, P-diphenylphosphino acetic acid determined. Finally, an inexpensive highly reproduceable differential thermal analysis device was designed and, coupled with the technique of dynamic gas evolution, used to determine the decomposition patterns of a series of cyano and nitrosylcyano transition metal complexes. This device was used extensively in characterizing other compounds produced during the study. (Author)
