[ReOCl3(PPh_3)_2]与水杨醛肟反应，意外地得到了[ReCl4(OPPh_3)_2](1)和[ReOCl_2(PPh_3)(η_2-OC_6H_4-2-CHNH)](2)。Re(IV)配合物1的晶体结构由离散的单核单元组成。Re与OPPh3基团的四个氯化物和两个反式氧结合。2的晶体结构也是单核的，Re(V)中心的几何构型由一个末端氧基、两个顺式氯化物、PPh3的磷以及苯氧亚胺配体[OC6H4-2-CHNH]−的氮和氧给电子体定义。
The reaction of [ReOCl3(PPh3)2] with salicylaldoxime unexpectedly yields [ReCl4(OPPh3)2] (1) and [ReOCl2(PPh3)(η2-OC6H4-2-CHNH)] (2). The crystal structure of the Re(IV) complex 1 consists of discrete mononuclear units. The Re site is bound to four chlorides and two trans oxygens of the OPPh3groups. The crystal structure of 2 is also mononuclear with the geometry of the Re(V) center defined by a terminal oxo-group, two cis chlorides, the phosphorus of the PPh3, and the nitrogen and oxygen donors of the phenoxyimino ligand [OC6H4-2-CHNH]−.
