Abstract:

Dioctylphosphinates of the bivalent first-transition-series elements from chromium through zinc have been prepared and characterized. The variety of forms found is discussed. CobaltII, ironII, and manganeseII yield a form based on octahedral centers which requires multiple sharing of some individual phosphinate oxygens. ChromiumII and nickelII may give similar derivatives. Uranyl phosphinates can be divided into two groups based on solubility. The viscosity and molecular weight data obtained for some of the soluble species indicate that they are polymeric although their solution behavior is not ideal. Infrared and Raman spectra suggest that the uranyl oxygen atoms are not shared in the soluble species and consequently that the bridging is via phosphinate groups. It has proved possible to prepare flexible, strong, crystalline films of the chromium trisphosphinate CrOPCH3C6H5O2OPC8H172O reproducibly. Author
