Je. Joachim et al., ORGANOMETAL CHEMISTRY OF TECHNETIUM .8. TECHNETIUM(I) CARBONYL-COMPLEXES WITH POLYPYRAZOL-1-YLBORATO LIGANDS IN COMPARISON WITH MN AND RE ANALOGS, Journal of organometallic chemistry, 448(1-2), 1993, pp. 119-129
The compounds HB(C3H3N2)3Tc(CO)3 and HB(3,5-Me2C3HN2)3Tc(CO)3 have bee
n synthesized for the first time, and their molecular and crystal stru
cture as well as the structures of the known analogous compounds of ma
nganese and rhenium determined by single-crystal X-ray diffraction. Th
e IR-, H-1-NMR-, C-13-NMR-, UV- and EI-MS-spectroscopic data are discu
ssed in correlation to the electric dipole moment and the charge distr
ibution within the molecule.
