Sample text

The Tc-Tc IR and Raman stretching frequencies of cis-[T~,(OAc)~Cl,L~l are lowered with increasing donor strength of the axial ligand L (240). Magnetic studies of [Tc2I6+complexes show only temperature-independent paramagnetism (150). - E. CARBOXYLATO AND P-DIKETONATO COMPLEXES Technetium(II1) complexes with aminocarboxylato ligands have been reported but none are well characterized (2411. 99mTc-iminodiacetate complexes formed with 2,6-alkylphenyl [ArNHCOCH2N(CH2C00)212ligands are used to image the hepatobiliary system.

The Sn" center is six coordinate, with the three chloro ligands in a fuc arrangement, and, in addition to the hydroxy bridge, two oxime oxygens complete the octahedral coordination sphere (2611. It may be noted that a + 3 oxidation for Tc is also consistent with an 18-electron seven-coordinate species. 3 ppm (255). A variety of seven-coordinate Re analogs of BATOs, uncapped [Re"'C1(cdoH),(cdoH~~],and monocapped [Re"'Cl(cdo)(cdoH),BR] has been prepared. Yields from Re0,- are low but [ReC13(MeCN)(PPh,),] is a suitable starting material.

E. CARBOXYLATO AND P-DIKETONATO COMPLEXES Technetium(II1) complexes with aminocarboxylato ligands have been reported but none are well characterized (2411. 99mTc-iminodiacetate complexes formed with 2,6-alkylphenyl [ArNHCOCH2N(CH2C00)212ligands are used to image the hepatobiliary system. A variety of Tc(II1) acac complexes and substituted analogs has been prepared by substitution/reduction of [TC'~X,(PR,),]and [TcrVX6Iz-or by S z 0 2 - reduction of Tc0,- in the presence of the ligand. A variety of sixcoordinate tris complexes of monothio-P-diketonates has been prepared by substitution of [Tc(tu),]Cl, in refluxing methanol and characterized by IR, electronic, and mass spectrometry; 'H NMR; and, for the phenyl derivative [Tc{SC(Ph)CHC(Ph)O},],a crystal structure determination (251, 252).
