摘　　要：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 pyridyl groups of dps ligands form a propellershaped 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.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 pyridyl groups of dps ligands form a propellershaped 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.
