Neutral fac-[Re(NNN)(CO)3] complexes with NNN tridentate ligands containing pyrrole or indole

Abstract New neutral fac -ReNNN(CO) 3 complexes where NNN are the Schiff base tridentate ligands N-(1H-pyrrol-2-ylmethylene)-2-(pyridin-2-yl)ethanamine (complex 1) and N-(1H-indol-2-ylmethylene)-2-(pyridin-2-yl)ethanamine (complex 2) were synthesized and characterized by elemental analyses, infrared and 1 H and 13 C NMR spectroscopies. The molecular structure of complex 1 was confirmed by X-ray crystallographic analysis that revealed a distorted octahedral geometry around Re.
