| Hexanuclear clusters are an interesting area of research because of their supraoctahedral structures and potential reactivities. Compared to single metal centers, little is known about the preparation and reactivity of these systems. One of the goals of our research group is to develop synthetic routes towards the preparation of new cluster complexes. This presentation will focus on our studies involving the substitution of the acetonitrile ligand coordinated to the rhenium selenide cluster, [Re6Se8(PEt3)5(NCCH3)]2+, with different N and O donor ligands. Specifically, we will discuss the synthesis and characterization of three novel complexes: [Re6Se8(PEt3)5(py)]2+, [Re6Se8(PEt3)5(OMe)]+, and [Re6Se8(PEt3)5(OPh)]+. Characterization techniques include: 1H, 13C, and 31P NMR spectroscopies, elemental analysis, mass spectrometry, and single crystal x-ray diffractometry. |
