X-Ray Powder Diffraction Pattern of Fe(II) Complex of 1,3,5-Hexachlorotriphosphazene

Abstract

The complex of 1,3,5-hexachlorotriphosphazene (HCTP),
(PNCI₂)₃ with iron(II) acetate has been synthesised and investigated
spectrometrically. The frequencies for P—N→M,  P—Cl₂,  P—N
ring along with CH₃COO^- ion have been observed in its IR and
laser Raman spectra. The electronic spectrum of the complex has
shown bands according to charge transfer,  ⁴T_1g ← ⁴A_1g and Pπ-Pπ
transitions inferring the hexadentated coordination of two
(PNCI₂)₃ rings to Fe(II)-acetate. X-ray diffractometric studies explain
the coordination of two (PNCI₂)₃ deformed  rings through
Fe²⁺ ion bridging having sandwich structure in a triclinic geometrical
packing.
