Synthesis and Crystal Structure of Cd(II) Complex with One-dimensional Chain Structure

The complex [Cd(L)2(H2O)2](ClO4)2·MeOH (1) [L=1,3,5-tris(3-pyridylmethoxy)benzene] was synthesized in methanol and characterized by elemental analysis and X-ray crystallography. The results of structural analysis indicate that the complex crystallizes in the triclinic, space group P1 with a=1.0571(5) nm, b=1.0590(5) nm, c= 1.2708(7) nm, α=87.460(16)°, β=81.895(17)°, γ=62.326(14)°, V=1.2470(11) nm3, Z=1, Dcalc=1.569 g·cm-3, F(000) =604, μ=6.26 cm-1, the final R=0.0352 and wR=0.0664. The coordination environment of Cd! is a distorted oc- tahedron, and each L ligand links two Cd! atoms using two of three pyridyl groups to generate an one-dimen- sional (1D) chain structure. The 1D chains are further connected by O- H…N, O- H…O and C- H…O hydrogen bonds to give a three-dimensional structure. CCDC: 283825.
