Diphosphonate ligands bridging

The 119Sn NMR spectrum of the adduct PhSnCl3 (EtO)2POCH2CH2PO(OEt)2 at —90 °C consists of a triplet at —557 ppm and a doublet of doublets at —551 ppm with approximately 5 1 relative intensities. These resonances were attributed to isomers of the hexacoordinate complex301,1056. The first isomer has two equivalent phosphorus atoms in the tin coordination sphere and consists of cis-fac octahedra in accordance with the preferred cis -bridging behavior of the ethylene-diphosphonate ligand. The second isomer with nonequivalent phosphorus atoms consists of cis-mer octahedra125. [Pg.1168]
