  Structural flexibility of titanocene diselenolene complexes: Combined structural and VT NMR investigations

  摘要：

  A comparative investigation on five different Cp2Ti(diselenolene) complexes, i.e. Cp2Ti(Se(2)C(2)Z(2)) (Z=-CO2Me), Cp2Ti(Se(2)C(2)Z(CF3), CP2Ti(bds) (bds = 1,2-benzene-diselenato), CP2Ti(dsit) (dsit = 1,3-dithiole-2-thione-4,5-diselenato) and CP2Ti(ddds) (ddds = 5,6-dihydro- 1,4-dithiine-2,3-diselenato) is performed based on structural and variable-temperature NMR data. Preparation Of Cp2Ti[Se(2)C(2)Z(CF3)] involves the reaction of CP2TiSe5 with an excess of methyl-4,4,4-trifluorotetrolate while CP2Ti(bds) is obtained from the bds(2-) diselenolate and Cp2TiCl2. Their X-ray crystal structures have been determined, showing that Cp2Ti(bds) is not isostructural with the sulfur analog Cp2Ti(bdt). Similarly the structures Of Cp2Ti(dsit) and Cp2Ti(Se(2)C(2)Z(2)) were also determined from single crystal X-ray diffraction. All complexes exhibit a strong folding of the metallacycle along the Se center dot center dot center dot Se hinge, ranking from 47.8 degrees in Cp2Ti (Se(2)C(2)Z(2)) to 52.3 degrees in CP2Ti(ddds). VT NMR investigations on CP2Ti[Se(2)C(2)Z(CF3)] and Cp2Ti(ddds), complementing earlier results on the other complexes, show that the largest activation energies and associated folding angles are observed with the most electron rich diselenolenes (ddds, bds), a behavior closely related to that observed earlier in dithiolene complexes.

  A (phenylenediselenolato)cobalt complex dimer, [Co(eta(5)-C5H5)(Se2C6H4)](2) (1), was synthesized by a reaction of carbonyl(eta(5)-cyclopentadienyl)diiodocobalt(III) ([Co(eta(5)-C5H5)I-2(CO)]) with poly(o-diselenobenzene). The structure of 1, determined by single-crystal X-ray crystallography, was found to be located in the space group of P2(1)/c (No. 14), with a = 9.3346(5) Angstrom, b = 11.6477(g) Angstrom, c = 10.2179(5) Angstrom, beta = 111.491(1)degrees, and Z= 2. Covalent Co-Se bonds bridge the metal centers. In solution, dimers and monomers coexist at equilibrium. The dissociation equilibrium constant of 1 in solution was evaluated by H-1 NMR spectra at several temperatures between 20 and 80degreesC. Dissociation enthalpies/entropies were found to be 50/110, 60/120, and 88 W mol(-1)/200 J K-1 mol(-1) in dimethyl sulfoxide-d(6), benzene-d(6), and chloroform-d(1), respectively.

  [(bpy)Pt(bds)], 1, (bpy-2,2'-bipyridine,bds-1,2-benenediselenolene) was prepared in good yield by the reaction of [(bpy)PtCl2] with bdsNa(2), which was generated in situ by reduction of oligomeric [bds](n). The analogous nickel complex [(bpy)Ni(bds)] (2), was generated in a similar fashion but could not be isolated cleanly. UV-Vis and electrochemical examination of these complexes show that the substitution of selenium atoms for sulfur atoms found in the related dithiolene complexes [(bpy)Pt(bdt)] (3), and [(bpy)Ni(bdt)] (4) (bdt= 1,2-benzenedithiolene) results in a small, but significant, alteration of the optical and electronic properties of this class of complexes. 1 was structurally characterized as both its CH2Cl2 solvate (P2(1)/n - a=8.5298(10) Angstrom, b=11.3461(2), c=19.1864(2), beta=99.309(10)degrees, V=1832.40(4) Angstrom(3), Z=4) and its DMSO solvate (P2(1)/c-a=11.1725(10) Angstrom, b=20.7304(10) Angstrom, c=8.3882(10) Angstrom, beta=99.926(10), V=1913.71(3) Angstrom(3), Z=4). With the exception of the incorporation of lattice solvent, both structures of 1 are essentially identical to that observed for 3 and 4 at both the molecular and supramolecular level.
