  摘要：

  A study of steric effects of the ligands R(2)PCH(2)PR(2), R = aryl, on the formation and chemistry of the clusters [Pt-3(mu(3)-CO)(mu-R(2)PCH(2)PR(2))(3)(O2CCF3)](+), 4, and [Pt-3(mu(3)-CO)(mu-R(2)PCH(2)PR(2))(3)](2+), 8, is reported. When R = 2-MeC(6)H(4), reduction of [Pt(O2CCF3)(2)(R(2)PCH(2)PR(2))] by CO/H2O gave only the binuclear complex [Pt2H(CO)(mu-R(2)PCH(2)PR(2))(2)](+), but with smaller groups R, further reduction to 4 (R = 4-MeC(6)H(4), 3-MeC(6)H(4), 3,5-Me(2)C(6)H(3), 3,5-F2C6H3, 3,5-Cl2C6H3) or to [Pt-4(mu-CO)(2)(mu-H)(mu-R(2)PCH(2)PR(2))(3)(R(2)PCH(2)PR(2))](+) (R = 4-MeC(6)H(4), 3,5-F2C6H3) occurred. The complexes were characterized spectroscopically and for 4(CF3CO2), R;= 3,5-Cl2C6H3, crystallographically [C80H42Cl24F6O5P6Pt3 . 0.5CH(2)Cl(2) . 1.5H(2)O, monoclinic, P2(1)/n, a = 23.365(4) Angstrom, b = 24.599(4) Angstrom, c = 19.141(7) Angstrom, beta = 102.44(2)degrees, Z = 4, R = 0.0727]. The complexes 8 can all form adducts with I-, SCN-, and CF3CO2- though evidence is presented that coordination of CF3CO2- is reversible in solution when R = 3,5-Cl2C6H3. Reactions of 8 with the ligands L = PPh(3), PMePh(2), P(OPh)(3), and P(OMe)(3) to form the adducts [Pt-3(mu(3)-CO)(mu-R(2)PCH(2)PR(2))(3)L](2+) are reversible, and the position of equilibrium depends on the steric effects of R, indicating the steric sequence R = 4-MeC(6)H(4), 3-MeC(6)H(4) < 3,5-Me(2)C(6)H(3) < 3,5-F2C6H3 < 3,5-Cl2C6H3.

  Synthesis, Photophysics, and Transient Absorption Spectroscopic Studies of Luminescent Copper(I) Chalcogenide Complexes. Crystal Structure of [Cu₄(μ-dtpm)₄(μ₄-S)](PF₆)₂ {dtpm = Bis[bis(4-methylphenyl)phosphino]methane}

  摘要：

  A luminescent copper(I) sulfide cluster [Cu-4(mu-dtpm)(4)(mu(4)-S)](PF6)(2) (3) {dtpm = bis[bis(4-methylphenyl)-phosphino]methane} has been synthesized and characterized by X-ray crystallography. Its photophysical and electrochemical properties have also been studied. The long-lived photoluminescence of 3 is assigned to originate from an excited state with a parentage of large ligand-to-metal charge-transfer LMCT [(S2-) --> Cu-4] character, with mixing of metal-centered MC [(ds/dp) Cu(I)(4)] state, The phosphorescent state of 3, as well as those of its analogues [Cu-4(mu-dppm)(4)(mu(4)-S)](PF6)(2) (1) and [Cu-4(mu-dppm)(4)(mu(4)-Se)](PF6)(2) (2), have been found to undergo facile electron-transfer reactions with different pyridinium accepters, which have been investigated with nanosecond transient absorption spectroscopy. Crystal data for 3: a = 37.38(1) Angstrom, b = 15.905(7) Angstrom, c = 27.761(5) Angstrom, beta = 128.69(1)degrees, V = 12881(6) Angstrom(3), Z = 4.
