The complex is a centrosymmetric [Cd2L2Cl4(MeOH)2] dinuclear structure and the Cd centre is in a distorted octahedron geometry. The crystal is in triclinic system, space group P1, with a=0.752 2(4) nm, b=1.043 1(5) nm, c=1.097 3(6) nm, α=66.11(2)°, β=72.48(2)°, γ=70.28(2)° and Z=1. The most striking feature of this complex is the formation of a 3D network bridged through the intermolecular N-H...O, O-H...O, C-H...O and C-H...Cl hydrogen bonds and stabilized via intermolecular π-π stacking interactions.

The title compound has the formula C22H28Cl2Cu2N8O11. It consists of dinuclear units with bridging methoxo groups. The ligands 2-amino-pyridine and 2-amino-6-hydroxyl-pyridine are linked to each copper via the pyridine N atoms respectively, providing a square planar CuN2O2 unit. The ClO4- anions in the title compound are semi-coordinated to copper ion at the distance of 0.265 83(4) nm (Cu-O(ClO4-). The Cu-Cu distances within the dinuclear units are 0.299 79(9) nm with Cu-O-Cu angles of 102.27(9)°. The structures are stabilized by intramolecular H-bonds between the amino hydrogen atoms and oxygen atoms. Based on crystal data, quantum chemistry calculation on DFT/B3LPY level was used to reveal the electronic structure of the title compound. CCDC: 270807.展开更多
