摘要 A new complex [Cu(L)(1,10-phen)]_n(1, L = N-3-pyridine sulfonyl amino acid) has been synthesized and characterized by IR, elemental analysis and X-ray diffraction analysis, and its crystal belongs to monoclinic, space group P2₁/c with α = 11.481(2), b = 18.094(4), c = 8.5198(17) Å, β = 102.26(3)°,V = 1729.5(6) Å³, Z = 4, D_c = 1.759 g/cm³, F(000) = 932, µ = 1.422 mm^-¹, R = 0.0368and wR = 0.0893. In 1, the Cu(II) ion adopts a slightly distorted five-coordinated square pyramidal geometry. The L^2- ligand adopts O of the carboxyl bridging adjacent Cu(II)units to form an infinite chain structure along the c axis. Also, π-π stacking interactions between the adjacent chains expanded the 1-D structures into a 3-D supramolecular structure.

Abstract：A new complex [Cu(L)(1,10-phen)]_n(1, L = N-3-pyridine sulfonyl amino acid) has been synthesized and characterized by IR, elemental analysis and X-ray diffraction analysis, and its crystal belongs to monoclinic, space group P2₁/c with α = 11.481(2), b = 18.094(4), c = 8.5198(17) Å, β = 102.26(3)°,V = 1729.5(6) Å³, Z = 4, D_c = 1.759 g/cm³, F(000) = 932, µ = 1.422 mm^-¹, R = 0.0368and wR = 0.0893. In 1, the Cu(II) ion adopts a slightly distorted five-coordinated square pyramidal geometry. The L^2- ligand adopts O of the carboxyl bridging adjacent Cu(II)units to form an infinite chain structure along the c axis. Also, π-π stacking interactions between the adjacent chains expanded the 1-D structures into a 3-D supramolecular structure.
