Abstract
N-Alkanol intercalation complexes of iron(III) oxide chloride FeOCl · a n-CxHx+1OH (x = 1-18) are obtained from the amine intercalates by replacement reaction or by a "propping-open" procedure. The alkanol content is slightly variable with a = 0.54 in the alkanol richest phases and 0.46 after heating to 110 °C. In the alkanol richest phases the long chain alkanol molecules (x ≤ 12) form bilayers in the interlayer region of the FeOCl with the major part of each chain in all trans conformation and perpendicular to the layers of the host lattice. The complexes undergo a series of reversible phase transformations on heating. The arrangement of short chain alkanols (x ≤ 6) is less regular. At higher temperatures ( > 130 °C) condensation to FeO(OR)nCl1-n is observed. The alkoxylated derivatives are also capable of forming intercalation complexes.Keywords
