![عکس صفحه اول مقاله: Monomeric complexes of Re(CO)3+ ion with tridentate N∩N∩O−ligands — Schiff base derivatives of salicylic aldehyde Monomeric complexes of Re(CO)3+ ion with tridentate N∩N∩O−ligands — Schiff base derivatives of salicylic aldehyde](/preview/png/1303574.png)
• Complexes of Re(CO)3+ ion with tridentate N∩N∩O ligands have been synthesized.
• The complexes have been characterized using EI-MS, UV-vis, and IR spectroscopy.
• Their structures have been confirmed by means of X-ray investigations.
• Three different coordination modes have been found for the studied N∩N∩OH ligands.
Simple synthetic procedures, reactions of Re(CO)5Cl with potentially tridentate N∩N∩OH ligands (Schiff bases prepared from aliphatic or aromatic amines and salicylic aldehyde) lead to formation of monomeric complexes of fac-Re(CO)3+ ion. Three obtained complexes have been characterized by means of elemental analyses and IR, UV–vis, and EI-MS techniques. Molecular structures of the synthesized species were investigated using X-ray diffraction measurements. Depending on the nature of N∩N∩OH ligand the investigated Schiff bases form with fac-Re(CO)3+ ion bidentate or tridentate chelates with N∩N, N∩O− or N∩N∩O− coordination types.
A simple synthetic procedure (reaction between Re(CO)5Cl and the title N∩N∩OH ligand in boiling toluene) leads to novel monomeric fac-Re(CO)3+ complexes.Figure optionsDownload as PowerPoint slide
