  摘要：

  Treatment of 1,4-{2,3,4-(Meo)3C6H2C(H) = N-}2C6H4 (a) or 1,4-{4,5-(OCH2O)C6H3C(H) = N-}2-C6H4 (b) with palladium(II) acetate gave the cyclometallated acetato-bridged complexes [1,4-{Pd[2,3,4-(MeO)3C6HC(H) = N](O2CMe)}2C6H4]n (1a) and [1,4-Pd[4,5-(OCH2O)C6H2C(H) = N](O2CMe)}2-C6H4]n (1b). These were converted into the analogous halide-bridged complexes by treatment with NaX (2a, 2b X = Cl; 3a, 3b X = Br). Reaction of a or b with PdCl2 also affords the chloro-bridged complexes 2a and 2b, which reacted with LiBr to give the bromo-bridged complexes 3a and 3b. The structure of 3a is described. This is the first example of a structurally characterized tetranuclear cyclometallated bromo-bridged palladium(II) complex. Crystals are triclinic, space group P1BAR, with a 1109.1(4), b 1181.5(4). c 1481.5(5) pm, alpha-77.33(3), beta-80.04(3), gamma-82.50(3)-degrees, U 1.857(1) nm3, Z = 1, R = 0.0558 and R(W) = 0.0610, for 3871 independent reflections with I > 2.0-sigma(I). The structure is a centrosymmetric tetranuclear palladium(II) dimer with symmetrically bridging bromine atoms and non-bonding Pd...Pd distance of 366.2(5) pm.
