  摘要：

  A new 1,3,4-oxadiazole bridging bent organic ligand, 2,5-bis{5-methyl-2-[(4- pyridyl)methoxy]phenyl}-1,3,4-oxadiazole, C28H24N4O3, L, has been used to create three novel one-dimensional isomorphic coordination polymers, viz. catena-poly[[[dichloridomercury(II)]-mu-2,5-bis{5-methyl-2-[(4- pyridyl)methoxy]phenyl}-1,3,4-oxadiazole] methanol monosolvate], {[HgCl2(C28H24N4O3)]center dot CH3OH}(n), catena-poly[[[dibromido-mercury(II)]-mu-2,5-bis{5-methyl-2-[(4-pyridyl)methoxy]phenyl}-1,3,4-oxadiazole] methanol monosolvate], {[HgBr2(C28H24N4O3)]center dot CH3OH}(n), and catena-poly[[[diiodidomercury(II)]-mu-2,5-bis{5-methyl-2-[(4-pyridyl)methoxy] phenyl}-1,3,4-oxadiazole] methanol monosolvate], {[HgI2(C28H24N4O3)]center dot CH3OH}(n). The free L ligand itself adopts a cis conformation, with the two terminal pyridine rings and the central oxadiazole ring almost coplanar [dihedral angles = 5.994 (7) and 9.560 (6)degrees]. In the Hg-II complexes, however, one of the flexible pyridylmethyl arms of ligand L is markedly bent and helical chains are obtained. The HgII atom lies in a distorted tetrahedral geometry defined by two pyridine N-atom donors from two L ligands and two halide ligands. The helical chains stack together via interchain pi-pi interactions that expand the dimensionality of the structure from one to two. The methanol solvent molecules link to the complex polymers through O-H center dot center dot center dot N and O-H center dot center dot center dot O hydrogen bonds.
