Abstract

The reaction of 1,3-bis(tetrazol-1-yl)-2-propanol (btzpol) with Fe(BF₄)₂ · 6H2O in acetonitrile yields the remarkable 2D coordination polymer [Fe^II(btzpol)_1.8(btzpol-OBF₃)_1.2](BF₄)_0.8 · (H₂O)_0.8(CH₃CN) (1). This compound has been structurally characterized using an X-ray single-crystal synchrotron radiation source. The iron(II) centers are bridged by means of double btzpol bridges along the c direction, and by single btzpol bridges along the b direction. The reaction of part of the ligand with the counterion has forced the compound to crystallize in this extended two dimensional structure. The compound shows spin-transition properties, both induced by temperature and light, with T_½ = 112 K and T(LIESST) = 46 K, respectively. The relaxation of the metastable high-spin state created by irradiation is exponential, following an Arrhenius type behavior at high temperature, and dominated by a temperature independent tunneling process at lower temperatures.
