in the case of 3, while 4 contains monodentate P-bound L(2) both complexes contain Re---Re bonds. The synthon cis-Re(2)(mu-O(2)CCH(3))(2)Cl(4)(H(2)O)(2) reacts with ligands L(1), L(2), 2,6-bis(diphenylphosphinomethyl)pyridine (L(3)), bis[2-(diphenylphosphino)ethyl]amine (L(4)), and N,N-bis[2-(diphenylphosphino)ethyl]trimethylacetamide (L(5)) to give the paramagnetic complexes Re(2)(mu-O(2)CCH(3))Cl(4)(eta(3)-L(n))
四重结合的dirhenium(III)配合物(n-Bu(4)N)(2)Re(2)Cl(8)与三齿配体反应,该配体包含基本上为平面的P,O,P供体,可提供配合物Re(2 )Cl(6)(eta(3)-L(1))(3)(L(1)=双[2-(二苯基膦基)苯基]醚)和(n-Bu(4)N)[Re(2 )Cl(7)(eta(1)-L(2))](4)(L(2)= 4,6-双(二苯基膦基)二苯并呋喃)。光谱和电化学数据支持非对称结构Cl(4)ReReCl(2)(eta(3)-L(1))在3的情况下,而4包含单齿P结合的L(2)两种配合物均包含Re-- -重新债券。合成子顺式(2)(mu-O(2)CCH(3))(2)Cl(4)(H(2)O)(2)与配体L(1),L(2)反应, 2,6-双(二苯基膦基甲基)吡啶(L(3)),双[2-(二苯基膦基乙基)乙基]胺(L(4))和N,N-双[2-(二苯基膦基)乙基]三甲
