Synthesis, Structure, and Magnetic Property of a New Co(II) Complex Based on 5-Methylisophthalic Acid and 1,6-Bis(triazol)hexane

Abstract

A new complex, {[Co₂(mip)₂(bth)₂](H₂O)_0.5}_n (1), [H₂mip = 5-methylisophthalic acid; bth = 1,6-bis(triazol)hexane], has been synthesized by hydrothermal reaction of Co(II) salt, H₂mip and bth ligands. The X-ray single-crystal structure shows that the complex belongs to the triclinic system, P-1 space group, a = 10.0919(16) Å, b = 14.222(2) Å, c = 15.322(2) Å, and α = 101.276(2)º, β = 102.717(2)º, γ = 94.896(2)º. The dinuclear Co(II) units are bridged by mip²⁻ to form a 1D double polymeric chain, which is further connected by bth to generate a 3D network. Moreover, the IR spectroscopy, elemental analysis and magnetic property of 1 were also characterized.
