| Abstract: | Using two novel bis-triazole ligands, 2,6-bis(1,2,4-triazole-4-yl)pyridine (L1) and 1,6-bis(1,2,4-triazole-1-yl)hexane (L2), one novel one-dimensional (1D) chain polymer Co(NCS)2(L1)2] n (I) and one two-dimensional (2D) coordination polymer Co(NCS)2(L2)2] n (II) have been synthesized and structurally characterized. The crystal crystallizes in the triclinic system for I, space group $P\bar 1$ , a = 7.879(6), b = 8.830(7), c = 9.837(8)Å, α = 70.230(11)°, β = 115.474(6)°, γ = 85.591(12)°, Z = 1. The crystal crystallizes in the mo-noclinic system for II, space group $P\bar 1$ , a = 7.879(6), b = 8.830(7), c = 9.837(8) α = 70.230(11)°, β = 115.474(6)°, γ = 85.591(12)°, Z = 1. The structural diversity of these two new Co(II) complexes vary from 1D chain to 2D porous supramolecular network, which may be ascribed to ligand directing effects under similar synthetic conditions (L1 contains rigid pyridine spacers while L2 contains flexible hexane spacers). |
