Abstract : The dioctylphosphinates Mr(OP(C8H17)2O)2, where M = divalent Cr, Mn, Fe, Ni, and Cu, have been prepared and characterized. In the solid state all appear to have octahedral or square planar coordination around the metal. The nickel derivative converts to a tetrahedral form above its melting point, whereas the copper and manganese derivatives change geometry upon dissolution. The infrared spectra of these materials in the PO2 stretching region suggest that several different types of metal phosphinate coordinate linkages are present. (Modified author abstract)
