  Reaction of [Pt{Fe(CO)3(NO)}2(PhCN)2] with diphenyl(2-pyridyl)phosphine selenide. Crystal structure of [(CO)3Fe(μ3-Se){Pt(CO)P(2-C5H4N)Ph2}2] and its theoretical study

  摘要：

  The reaction between the linear trinuclear complex [Pt{Fe(CO)(3)(NO)}(2)(PhCN)(2)] and Ph-2(2-C5H4N)PSe led to the isolation and characterization of the 46-electron cluster [(CO)(3)Fe(mu(3)-Se){Pt(CO)P(2-C5H4N)Ph-2}(2)] (1), whose structure has been determined by X-ray diffraction methods. The cluster typology, which consists of an open triangle Pt-Fe-Pt capped by a mu(3)-Se atom, is rather rare. The chemical bonding in I and in similar systems has been analyzed through density functional theory (DFT) and qualitative MO approaches. A strict analogy with the well understood L2M(mu acetylene) ML2 systems is invoked by considering I as formed by the (CO)(3)FedropSe tetrahedral unit stabilized by sidewise interactions of the triple bond with two d(10)-L2M fragments. Otherwise, the 18-electron (CO)(3)FedropSe monomer is unstable as an isolate molecule. This is confirmed by our DFT calculations that indicate how the well characterized dimer (CO)(3)Fe(mu-Se-2)Fe(CO)(3) lies as much as, approximately, 58 kcal mol(-1) deeper in energy. Finally, by considering an analogy with [L2M(mu-dichalcogen)ML2](0,+2) redox systems (M = Pd, Pt), reduction of 1 to a dianion has been hypothesized and the structure of the latter has been tentatively explored by DFT calculations.

  The chalcogenide ligands E=PPh2Py} (E = O, S, Se) were prepared by direct oxidation of diphenyl (2-pyridyl)phosphine using H2O2, S, and Se powder, respectively. The reaction of ligand with starting metal precursors [(arene)RuCl2](2) M = Ru, arene = benzene; p-cymene} and [Cp*MCl2](2) (M = Rh, Ir) afforded a series of cationic half-sandwich complexes, [(arene/Cp*) MClkappa(2)-(NE)-EPPh2Py)}](+). Reaction of O=PPh2Py with precursors yielded known complexes [(arene/Cp*)MCl kappa(2)-(PN)-PPh2Py)}](+) instead of expected complexes [(arene/Cp*)MClkappa(2)-(NO)-O=PPh2Py)}](+). All new complexes were isolated as PF6- counterion and characterized by spectroscopic techniques like FT-IR, NMR, mass, and UV-vis. Some representative complexes were structurally determined by X-ray crystallographic analysis, revealing typical three-legged piano stool geometry around the metal center with a five-membered metallacycle.

  The behavior of the Ph-2(2-C5H4N)PSe ligand in the reactions with Ru-3(CO)(12) and the mononuclear complexes MCl2(PhCN)(2) (M=Pd or Pt) has been investigated. The reaction with Ru-3(CO)(12) is characterized by P=Se bond cleavage, affording the 48-electron compound [Ru-3(mu(3)-Se)(mu-PPh2)(2)(mu-C5H4N)(mu(3)-C5H4N)(CO)(6)] (1), the open triangular 50-electron nido clusters [Ru-3(mu(3)-Se),(CO)(9-n) P(2-C5H4N)Ph-2}] (2 and 3, for n=1 and 2, respectively) and the octahedral 62-electron closo cluster [Ru-4(mu(4)-Se)(2)(CO)mu-P, N-Ph-2(2-C5H4N)P}] (4). The cluster 1 derives by the multiple fragmentation of two phosphine ligands on the metal triangle involving the P=Se and P-C bond cleavages. The molecular structure of 4 shows a short Ru...P non-bonding separation that can be viewed as a preliminary step towards the P-C bond cleavage. In the reactions with MCl2(PhCN)(2) (M=Pd, Pt) Ph-2(2-C5H4N)PSe remains intact affording mononuclear neutral complexes of the type MCl2N,Se-Ph-2(2-C5H4N)PSe}. The crystal structure of the palladium derivative 5 has been determined by X-ray diffraction methods. (C) 2003 Elsevier Science B.V. All rights reserved.
