摘要：

Four new diverse structural iron(II) coordination polymers, namely, [Fe(btx)(3)(H2O)(2)](ClO4)(2)center dot 2H(2)O center dot btx (1), [Fe(btx)(N(CN)(2))(2)(H2O)(2)] (2), [Fe(btx)(2)(SCN)(2)]center dot 0.5EtOH center dot CH3CN (3) and [Fe(btx)(2)(N(CN)(2))(H2O)](ClO4)center dot EtoH center dot H2O (4) [btx = 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene], are reported with their crystal structures and magnetic properties. Compounds 1 and 2 possess 1D chain bridged by btx ligands, while compounds 3 and 4 have similar 2D (4,4) sheet-like structure. Variable temperature magnetic susceptibility measurements indicate that all of these iron(II) polymers retain a high-spin ground state and the values of chi T-M at low temperature are attributed to the zero-field splitting of the iron(II) ions and weak antiferromagnetic coupling.
