The famous α-Fe active sites in Fe-zeolites have recently been revealed to correspond to mononuclear high-spin iron(ii) centres in square planar coordination environments. Here we report a first iron siloxide complex which represents a faithful structural and spectroscopic model of such sites. Notably, also an allogon with a distorted structure exists and could be crystallised.
最近发现，铁沸石中著名的α-Fe活性位点对应于四方平面配位环境中的单核高自旋铁（II）中心。在此，我们报道了首个铁硅氧化物配合物，它代表了此类位点的一个忠实的结构和光谱模型。值得注意的是，还存在一种结构扭曲的同素异形体，并且能够被结晶出来。
