Study by X-Ray Crystallography and Mossbauer-Spectroscopy of the Layered Compounds with 2-Dimensional Metal-Complex Iron(II) Tetracyanonickelate(II)
A new layered compound, Fe(H2O)(2)Ni(CN)(4).2G (G=1,4-dioxane) has been characterized by single crystal X-ray analysis and Fe-57 Mossbauer spectroscopy. The host layer comprises a close-2D network of [FeNi(CN)(4)](infinity), from which a pair of water ligands protrude above and below the layer at Fe(II). The guest molecules, 1,4-dioxane, are accommodated in the interlayer space. The Fe-57 Mossbauer parameters indicate the iron atoms are in Fe(II) high-spin states. The X-ray and Mossbauer data imply the Fe(II) atom is surrounded by four N atoms of bridged cyano groups and two O atoms of water.
