Crystal and molecular structure of technetium tricarbonylbromide complex with ethylenediamine [Tc(CO)3Br·en]

The paper deals with the X-ray diffraction analysis of the complex of technetium tricarbonylbromide with ethylenediamide [Tc(CO)3Br·en]. The crystals are of rhombic syngony, a=7.013(1), b=13.177(8), c=10.736(5)A, β=101.73(3), sp.group P21/n, Z=4, dcal=2.19 g/cm3. The crystal lattice is composed of isolated molecules of [Tc(CO)3Br·en] which have facial configuration. The calculation of full energy and bond ratios is performed for the given complex, its chloride analogue and their hypothetical meridian isomers by the RMC method. 7 refs.; 1 fig.; 3 tabs
