摘要：

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 angstrom in interlayer spacing compared to its monohydrate. Primary amines CnH2n+1NH2 (n = 3-8) 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 angstrom, which indicates that the alkyl chains of amine are packed as double layers with a tilt angle of 53-degrees with respect to the mean plane of the layer. The behavior of copper phosphonates was compared to those of Mn, Co, and Zn phosphonates.
