Complexes of phosphazenes with I{sub 2} have been prepared with molecular and polymeric phosphazene/I{sub 2} ratios ranging from 8 to 0.2. For brevity the phosphazenes are identified as follows: (NPCl{sub 2}){sub n}; (NP(OPr){sub 2}){sub n} (=(NP(OCH{sub 2}CH{sub 2}CH{sub 3}){sub 2}){sub n}); (NP(OCH{sub 2}CF{sub 3}){sub 2}){sub n} (=(NP(OTFE){sub 2}){sub n}); (NP(OC{sub 2}H{sub 4}OC{sub 2}H{sub 4}OCH{sub 3}){sub 2}){sub n} (=MEEP). Resonance Raman spectra indicate that polyiodides are formed for all but the (NPCl{sub 2}){sub n}-iodine system. Impedance measurements demonstrate high bulk conductivities near ambient temperature for the MEEP and (NP(OPr){sub 2}){sub n}-based systems. For all systems, the conductivity increases with increasing iodine loading.
