The complex Re2Cl4(μ-dppa)2 (dppa=Ph2PNHPPh2) has been reacted with EtCN and PhCN to afford the complexes [Re2Cl3(μ-dppa)2(NCR)2]PF6 (R=Et or Ph), [Re2Cl3(μ-HN2C2Et2)(μ-dppa)2(NCEt)]Cl and [Re2Cl3(μ-HN2C2Et2)(μ-dppa)2(NCEt)](PF6)2 which are derivatives of the [Re2]4+, [Re2]5+ and [Re2]6+ cores, respectively. This behaviour is similar to the reactions of Re2Cl4(μ-dppm)2 (dppm=Ph2PCH2PPh2) with monodentate
复合物Re 2 Cl 4(μ-dppa)2(dppa = Ph 2 PNHPPh 2)已与EtCN和PhCN反应,得到复合物[Re 2 Cl 3(μ-dppa)2(NCR)2 ] PF 6( R =的Et或pH),[回复2氯3(μ-HN 2 c ^ 2的Et 2)(μ-DPPA)2(NCET)] Cl和[回复2氯3(μ-HN 2 c ^ 2的Et 2)( μ-dppa)2(NCEt)] [PF 6)2它们分别是[Re 2 ] 4+,[Re 2 ] 5+和[Re 2 ] 6+核的衍生物。此行为类似于Re 2 Cl 4(μ-dppm)2(dppm = Ph 2 PCH 2 PPh 2)与单齿腈的反应。Re 2 Cl 4(μ-dppm)2的反应与多齿腈配体1,4-二氰基苯(1,4-DCB),1,4-二氰基丁-2-烯(1,4-DCBE)和三(2-氰基乙基)膦(CEP)也会形成这种化合物的络合物腈配
