关于多齿环配体与铼络合的结构和反应化学的资料有限，一些著名的例子是irans-[Re (0) 2 (cyclam)]+ 1和[Re (0)(L)(OMe) 2] C104, 2，其中L为2,2 ':6',2':6',2' -四分之一吡啶。我们最近的工作主要集中在环吡啶和联吡啶配体的亚胺鎓配合物的化学性质上，3-4这是很重要的，因为苯基过渡金属配合物作为合成和催化中间体是有用的。5,6此外，铼的许多氮和亚胺配合物表现出长寿命的发射电子激发态，我们希望在小分子活化中利用这一特性。因此，我们研究了苯基咪多苯配合物与多齿配体1,2 -二（2,2 '-联吡啶-6-基）乙烷（o-bpy）的络合8，并在这里报告了合成、电化学和结构性质。从本研究和以前的工作中，很明显，o-bpy配体能够稳定Re (V)和Ru （II）等多种金属的trans -bpy几何形状
Information concerning the structural and reaction chemistry of multidentate cyclic ligands complexed to rhenium is limited, some notable examples being irans-[Re (0) 2 (cyclam)]+ 1 and [Re (0)(L)(OMe) 2] C104, 2 where L is 2, 2': 6', 2": 6", 2"-quarterpyridine. Our recent efforts have focused on the chemistry of imidorhenium complexes with cyclic pyridyl and bipyridyl ligands, 3-4 which is important because of the usefulness of the phenylimido transition metal complexes as synthetic and catalytic intermediates. 5, 6 Additionally, many nitrido and imido complexes of rhenium exhibit long-lived emissive electronic excited states, a feature which we hope to exploit in small molecule activation. 7 Consequently, we have examined the complexation of a phenylimidorhenium complex with the multidentate ligand l, 2-bis (2, 2'-bipyridyl-6-yl) ethane (o-bpy), 8 and report here the synthesis and electrochemical and structural properties. From this and previous work, it is apparent that the o-bpy ligand is capable of stabilizing trans bpy geometries at metals as diverse as Re (V) and Ru (II). 9
