Popis:	A single pot reaction of rhenium decacarbonyl, dipyrrinato ligand (5-(4-methylbenzoate)-dipyrromethene, L1H) and an ancillary ligand (either triphenyl phosphine or pyridine) in mesitylene medium has yielded visible light absorbing complexes 1 and 2 having a general formula [L1Re(CO)3L2] (L1 = dipyrrinato ligand; L2 = PPh3 = 1; L2 = pyridyl = 2). The complexes were characterized using IR UV-Vis, NMR and HRMS techniques. Binding of fac-Re(CO)3 to L1H has significantly red-shifted the charge transfer band at 436 nm to 488-491 nm in the complexes 1 and 2. Compound 1 is previously reported, although here we report a single step process that is different from the two-step process known in the literature.
