  Arrigo, L.M.; Galenas, M; Bassil D.B.; Tucker, S.A.; Kannan, R.;   Katti, K.V., Barnes, C.L.; Jurisson, S.S.  Fluorescent   phosphinimine as possible precursor to an anionic and fluorescent   sensor for Tc-99.  Radiochimica Acta 2008   (96) 835-844.


  The trimethylsilyl-protected phosphinimines   (9-anthracenyl)Ph2P=NSiMe3 and   (l-naphthyl)Ph2P=NSiMe3 and the ion pairs   [(9-anthracenyl)Ph2P=NH2+][MO4-]   and   [(1-naphthyl)Ph2P=NH2+][MO4-]    with M = Re or Tc were synthesized and characterized by H-1 and   P-31 NMR, UV-Vis and fluorescence spectroscopy, elemental   analysis, and/or single crystal X-ray diffraction. Radiochemical   studies performed using Tc-99m and Re-186 as the tracers for   Tc-99 and Re found the selectivity of the phosphiniminium cations   for pertechnetate in the presence of a variety of anions found in   the environment to be excellent.. The crystallographic data   reported for the structures are as follows:    [(9-anthracenyl)Ph2P=NH2+][ReO4-]   (H21C26NO4PRe) 2, monoclinic (P2(1)/n), a= 11.3047(54 angstrom,   b= 16.3983(8) angstrom, = 12.2469(6) angstrom, =92.344(1)degrees,   Z =4; pairs   [(9-anthracenyl)Ph2P=NH2+][TcO4-]   (H21C26NO4PTc) 3, monoclinic (P2(1)/n), a = 11.3619(4) angstrom,   b = 12.2203(3) angstrom c = 25.7794(13) angstrom, beta=   92.162(1)degrees, Z = 4.
