    treatment of [Fe(κ3P,N,P-PNP)Cl2] with CO. With small PNP ligands, such complexes are not accessible directly owing to the formation of [Fe(κ3P,N,P-PNP)(κ2P,N-PNP)Cl]Cl. These complexes liberate the κ2-P,N-bound PNP ligand in the presence of CO to yield [Fe(κ3P,N,P-PNP)(CO)Cl2] in yields of less than 50 %. High yields are achieved by reacting FeCl2 with PNP ligands under a CO atmosphere. For structural and

    octahedral complexes cis- and trans-[Fe(PNP)(CO)(Cl)2], respectively, whereas with X = Br mixtures of cis and trans isomers are obtained. These transformations are accompanied by color and spin-state changes. CO binding is fully reversible in all cases, and heating solid samples of either cis- or trans-[Fe(PNP)(CO)(X)2] leads to complete regeneration of analytically pure [Fe(PNP)(X)2].

    已经制备了几种新的[Fe(PNP)X 2 ]类型的(II)配合物(X = Cl,Br),其包含基于2,6-二氨基吡啶和2,6-二氨基嘧啶的三齿PNP钳型配体。它们都表现出分子间的Fe-X··H-N氢键,形成固态的超分子网络。在X = Cl的情况下,这些化合物在固态和在溶液中均易于与气态CO反应,从而分别选择性地产生八面体配合物顺式和反式[Fe(PNP)(CO)(Cl)2 ]。 X = Br顺式和反式的混合物获得异构体。这些转换伴随着颜色和自旋状态的变化。在所有情况下,CO结合都是完全可逆的,加热顺式或反式[Fe(PNP)(CO)(X)2 ]的固体样品会导致分析纯[Fe(PNP)(X)2 ]的完全再生。。Mössbauer光谱证实了母体五坐标Fe(II)配合物(δ= 0.80(1)mm s -1)的高自旋性质,并且在与固体中的CO反应后转变为两种不同的低自旋八面体物种( δ= 0.13(1)mm
  • Kinetically Controlled Formation of Octahedral <i>trans</i>-Dicarbonyl Iron(II) PNP Pincer Complexes: The Decisive Role of Spin-State Changes

    Treatment of either cis-[Fe(PNP)(X-2)(CO)], trans-[Fe(PNP)(X-2)(CO)], or [Fe(PNP)X-2] (X = Cl, Br; PNP are tridentate pincer-type ligands based on 2,6-diaminopyridine and 2,6-diaminopyrimidine) with I equiv of AgBF4 in the presence of CO afforded selectively octahedral iron(I complexes of the type trans-[Fe(PNP)(CO)(2)X](+). The same reaction carried out with irons-trans-[Fe-PNP-iPr)(Cl)(2)(CO)] in the absence of CO affords also trans-[Fe-Te(PNP-/Pr)(CO)(2)Cl](+) together with unidentified paramagnetic species. This reaction involves an intermolecular CO transfer between coordinately unsaturated [Fe(PNP-iPr)(CO)(Cl)](+) intermediates. In all reactions studied, there was no evidence for the formation of cis dicarbonyl complexes. X-ray structures of representative complexes are presented. A detailed mechanism, based on DFT/B3LYP calculations, is presented, suggesting that upon irreversible removal of X transient cationic intermediates [Fe(PNP)(CO)(X)](+) of two conformations, one with the CO in the apical and the halide in the basal position (A) and vice versa (B), are formed. These adopt a singlet ground state in the case of A and a triplet ground state in the case of B. The formation of trans-[Fe(PNI)(CO)(2)X](+) is kinetically controlled, with A in the singlet ground state being the key intermediate. Pathways originating from complexes with a triplet ground state are "spin-blocked" (spin forbidden) or thermodynamically disfavored.
