Abstract

Based on the bis-triazole ligand 2, 6-bis(1, 2,4-triazole-4-yl)pyridine (L), the triazole-iron(II) complexes [Fe(L)₂(dca)₂(H₂O)₂]·2H₂O (1) (Nadca = sodium dicyanamide), {[Fe(μ₂-L)₂(H₂O)₂]Cl₂}_n (2), and {[Fe(μ₂-L)₂(H₂O)₂](ClO₄)₂·L·H₂O}_n (3) were isolated by solvent diffusion methods. When iron(II) salts and Nadca were used, compound 1 was isolated, which contains mononuclear Fe(L)₂(dca)₂(H₂O)₂ units. When FeCl₂ or FeClO₄ were used, one-dimensional (1D) cation iron(II) chains (2) and two-dimensional (2D) cation iron(II) networks (3) were isolated indicating anion directing structural diversity. Moreover, variable-temperature magnetic susceptibility data of 1-3 were recorded in the temperature range 2-300 K. The magnetic curve of complex 2 was fitted by using the classical spin Heisenberg chain model indicating anti-ferromagnetic interactions (J = -5.31 cm^-1). Obviously complexes 1-3 show no detectable thermal spin crossover behaviors, the lack of spin-crossover behavior may be correlated with FeN₄O₂ coordination spheres in 1-3.
