Buryak, V. Bandur, V. Zavadovskaya, D. Stepanishcheva] The structure of Ti(III) coordination polyhedrons in both individual NaPO3 and 70 mole % NaPO3-30 mole % NanX mixtures (X=PO3 3−, P2O7 4−, F−, Cl−) in the molten and solid states has been investigated on the basis of data from electronic absorption and ESR spectra. The formation of tetragonally distorted Ti(III) coordination polyhedrons with D4h symmetry coordinated only by (PO3 −)n chains with the following values of the spectroscopic parameters for the molten (and solid) states has been established in all the phosphate systems investigated: 10Dq=17,300 (18,000) cm−1 (Ds=50 cm−1, Dt=5600, g∥=1.959, g1=1.930, λ=93. cm−1). It has been shown that the greater is the extent of depolymerization of the phosphate chains in the melt, the stronger is the Ti(III) coordination polyhedron formed; the following relative series of the depolymerizing strength of the anions has accordingly been established: PO4 3−<P2O7 4−<F−<Cl−.
