What is Pentacoordinated complexes of organotellurium(IV) halides with tertiary phosphine selenides about?

The pentacoordinated tellurium(IV) complexes [R2TeC12 \* L] [R = C6HS or p-CH30CgH4; L = Ph,PSe, (p-MeC,H,),PSe, Bu,PSe or Ph2P(Se)(CH2),(Se)PPh2] were obtained by the reaction of R,TeC12 with L under anhydrous conditions. The complexes have been characterized by spectral (IR, ' H NMR and 3' P NMR) studies. The reaction of RTeCl, and L, however, yields tellurium/selenium metal. ' 5(31P-77Se) coupling constant data suggest complexation. In case of bidentate donor bases only one donor site is used in coordination. The complexes possess distorted octahedral geometry around a central tellurium atom which is surrounded by five groups and one vacant site occupied by a lone pair.
