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.展开更多

The complex crystallizes in monoclinic system with space group Cc, a=0.845 1(17) nm, b=1.836 5(4) nm, c=2.715 8(5) nm, β=93.99(3)°, V=4.204 8(15) nm3, Z=4, R1=0.037 7 and wR2=0.076 9. The coordination geometry of the Pd atom in the cation is a slightly distorted square planar, with one pyridyl N and two N atoms of the diethylamine ligand, together with one Cl atom. The dihedral angle between the square planar (N3PdCl) and the pyridyl ring is 10.3(4)°. CCDC: 623421.展开更多
