We synthesized a new 4,4 ' -bipyridyl-based building block, 1,4-(di-4-pyridyl) methoxy benzene (bpmob), which appears as two kinds of isomers: trans- and cis-modes. The building block self-assembled into one-dimensional coordination polymer [Cd(NO3)(2) (cis-bpmob)(2)](n) . [Cd(NO3)(2)(trans-bpmob) (H2O)](2n) (I) with Cd(II), and two-dimensional coordination polymer [Co(NCS)(2)(trans-bpmob)(2)](n) (II) with Co(II). Polymer I consists of two parts: double zig-zag linear chain and ladder-like one-dimensional chain, trans- and cis-modes exist simultaneously in the polymer. Polymer II shows a two-dimensional plane network structure with rhombohedral grids, and the polymer also exhibits layered packing in its solid-state structure.
