A coordination polymer {[Co(N3)2(dps)2]·0.5H2O}n (1) (dps=dipyridin-4-ylsulfane) with one dimensional chains has been synthesized and the structure and magnetic properties were characterized. Complex 1 crystallizes belongs to monoclinic system and has space group P21/c. The CoⅡ ion is six-coordinated and located at a compressed octahedral environment due to the Jahn-Teller effect. The ligand of dps bridges between Co Ⅱ ions producing the infinite chains of Co ? ? ? Co along a direction and, interestingly, four pyridy1 groups of dps ligands form a propeller-shaped coordination geometry around CoⅡ ion with the same spiral within the chain. These 1D chains are further linked through the hydrogen bonds to generate a 3D supermolecular network. Magnetic studies indicated that complex 1 shows very weak antiferromagnetic coupling between CoⅡ ions in low temperature.
