2+ cations. Other complexes synthesized are trans -[MoL 2 (dmpe) 2 ], L = NEt 2 , SPh; trans -[VL 2 (dmpe) 2 ], L = CN, SCN, CS 2 ; [VL 2 (dmpe) 2 ] + , L = EtCN, t BuNC; [VCl( t BuNC) (dmpe) 2 ] + and [V(NCMe) 6 ] 2+ . Nuclear magnetic and electron spin resonance spectra of the compounds are reported and the X-ray crystal structure of four of the compounds listed in the title are described.
摘要研究了其他各种
配体取代配合物中的
氯化物,反式-[
MCl 2(dmpe)2] M = Mo和V,dmpe = 1,2-双(二
甲基)膦基
乙烷。对于Mo,
乙腈产生反式-[MoCl(NCMe)(dmpe)2] +,其异构体具有η1-或η2 -MeCN。它们与
甲醇反应,得到
钼(IV)乙基亚
氨基配合物[MoCl(NEt)(dmpe)2] +。Mo和V均给出[M(NCMe)2(dmpe)2] 2+阳离子。合成的其他配合物是反式-[MoL 2(dmpe)2],L = NEt 2,
SPh; n = 1。反式-[VL 2(dmpe)2],L = CN,SCN,CS 2;[VL 2(dmpe)2] +,L = EtCN,t BuNC; m = 1。[
VCl(t BuNC)(dmpe)2] +和[V(NCMe)6] 2+。报告了化合物的核磁共振和电子自旋共振谱,并描述了标题中列出的四种化合物的X射线晶体结构。
