Abstract

A bitopic ligand 2-hydroxy-1-(tetrazol-1-yl)-3-(tetrazol-2-yl)propane (12pbtzOH) was synthesized and reacted with Fe(ClO4)(2).6H2O, giving a 1D coordination polymer {Fe(12pbtzOH)2(CH3CN)2(2).2CH3CN} infinity that exhibits a high-spin to low-spin transition (T1/2(downward arrow)=T1/2(upward arrow) congruent with 104 K). This is an unprecedented example of an iron(II) complex containing Fe(tetrazolyl) 4(MeCN)2 cores.

摘要

合成了一种双位点配体2-羟基-1-(四唑-1-基)-3-(四唑-2-基)丙烷(12pbtzOH)，并使其与Fe(ClO4)2·6H2O反应，得到一维配位聚合物{Fe(12pbtzOH)2(CH3CN)22·2CH3CN}∞，该聚合物表现出高自旋到低自旋的转变(T1/2(向下箭头)=T1/2(向上箭头)≈104 K)。这是一个前所未有的含有Fe(四唑基)4(MeCN)2核的铁(II)配合物的例子。
