Abstrakt

Ni(II)/Fe(III) cyanometallate structures with Si(OR)(3)-substituted bis(2-aminoethyl)-1,3-propanediamine or 1,4,8,11-tetraazacyclotetradecane (cyclam) blocking ligands at Ni(II) were prepared and embedded in SiO2 by means of sol-gel processing with Si(OEt)(4). The cyanometallates were microcrystalline before sol-gel-processing, and a double-chain structure is proposed for the silyl-substituted [Ni(tetramine)](3)[Fe(CN)(6)](2) derivatives. The 3D arrangement is lost during sol-gel processing, although Fe(III)-C=N-Ni(II) structures are retained in the gels, as proven by FTIR and SWAXS studies. The obtained gels show paramagnetic behavior.
