Ferrous flatland: Two flattened FeIIO4 units that share an edge are found in the title compound (see structure). They are spanned by tripodal silanolate ligands, which form in situ from a trisilanol if iron ions are available for complexation. The compound approaches the situation in the natural ironsilicate gillespite or in certain ceramics where squareplanar FeO4 units have also been found.
亚铁平地:在标题化合物中找到两个具有边线的扁平Fe II O 4单元(请参见结构)。它们由三脚架硅烷醇酸酯配体跨越,如果铁离子可用于络合,则该配体由三硅烷醇原位形成。该化合物接近天然硅酸铁硅镁石或某些陶瓷中也发现了方形平面FeO 4单元的情况。
