Manganese hydride complex structure

Evidence for rc(-l) in complex compounds appears in the synthesis of the carbonyl anion 1Tc(CO)5], the carbonyl hydride [HTc(CO)s]°, and the heteronuclcar carbonyl anion TcFe2(CO)i2] . Their existence was suggested by a comparison of their TR absorption bands with those of the corresponding compounds of manganese and rhenium, however, no structural determinations or magnetic measurements were reported.
