A combined experimental and DFT investigation on the structure and CO-releasing properties of mono and binuclear fac-Re^I(CO)₃complexes with 5-pyridin-2-ylmethylene-amino uracils

The synthesis, structure and CO-releasing properties of a number of new tricarbonyl rhenium(i) complexes with 5-substituted-6-amino-1,3-dimethyluracils are reported and their structural features discussed on the basis of both spectral and X-ray crystallographic analyses. The 5-substituent library includes -N[double bond, length as m-dash]CH-2py (DAAUPic) and -CH[double bond, length as m-dash]N-N[double bond, length as m-dash]CH-2py (FDUHzPic) as...
