The aim of this work was to study products produced in basic and acidic media upon atmospheric pressure and high-pressure carbonylation and to propose probable mechanism of reaction. It was found that tricarbonyltechnetium (I) fragment forms strong complexes with charged ligands. The polydentate anions (like citrate anion), which occupies three coordination places in octahedral technetium arrangement forms strongest complexes. So Tc (CO) 3 moiety in aqueous solutions exhibits properties of a typical d-element and a “soft” acid.
