INTERACALATION OF ALKYLAMINES INTO LAYERED COPPER PHOSPHONATES Academic Article

abstract

• Dehydration of layered copper phosphonates Cu(O3PR)H2O (R = CH3, C6H5, CH2C6H5) yields layered anhydrous salts Cu(O3PR) which show an increase of more than 1 in interlayer spacing compared to its monohydrate. Primary amines CnH2n+1NH2 (n = 38) were intercalated into anhydrous Cu(O3PCH3) and Cu(O3PC6H5). The copper methylphosphonate takes up 1 mol of amine forming Cu(O3PCH3)(RNH2), while 2 mol of amines were absorbed by copper phenylphosphonate. A plot of the interlayer distances of the intercalates vs the number of carbon atoms in the alkyl chain gives a straight line with a slope of 2.01 , which indicates that the alkyl chains of amine are packed as double layers with a tilt angle of 53 with respect to the mean plane of the layer. The behavior of copper phosphonates was compared to those of Mn, Co, and Zn phosphonates. 1993, American Chemical Society. All rights reserved.
