A new one-dimensional chain complex [Cu(N3)2(C6H8N2)]n (C6H8N2=(2-aminomethyl)pyridine) has been synth-esized and characterized by EA, FTIR and X-ray single-crystal structure analysis. The complex crystallizes in triclinic space group P1, with a=0.690 1(2) nm, b=0.825 1(3) nm, c=0.995 3(3) nm, α=67.154(5)°, β=72.898 (5)°, γ=65.462 (5)°, V=0.469 1 (3) nm3, Z=2. Magnetic susceptibility measurement indicates that there is a weak ferro-magnetic exchange coupling between Cu(Ⅱ) ions. CCDC: 686151.
A new copper(Ⅱ) complex, [CuL2Cl2]·4H2O, [L=3-ethyl-4-( p-methoxyphenyl)-5-(2-pyridyl)-1,2,4-triazole], was synthesized and characterized by X-ray crystallography and infrared spectroscopy. The complex crystallizes in triclinic system with space group P1, a=0.843 9(7) nm, b=0.965 5(8) nm, c=1.093 6(8) nm, α=84.026(19)°, β= 82.33(2)°, γ=89.167(19)°, V=0.878 3(12) nm3, Z=1 with final R=0.033 8. The copper atom lies in a distorted octah-edral environment with two bidentate chelating ligands (L) in the equatorial plane and two Cl-ions in the axial positions. The ligand L coordinates via one triazole nitrogen and one pyridine nitrogen atom. The molecules are stabilized by intermolecular hydrogen bonds in the crystal lattice. CCDC: 705817.
