Herein, we communicate the synthesis of a novel rhenium(I) complex, fac-[Re(CO)(3)(chrpychr)Br] (1) from the equimolar reaction between 2-(4-oxo-4H-chromen-3-yl)-5H-chromeno[2,3-d]pyrimidin-5-one (chrpychr) and [Re(CO)(5)Br]. The metal complex I was characterized via H-1 NMR-, IR- and UV-Vis spectroscopy and conductivity measurements. Single crystal X-ray analysis provides definitive confirmation in the structural elucidation of 1. DFT studies of 1 aided in the interpretation of its experimental IR spectrum.
