1-Decylphosphonic acid (1), ammonium 1-decylphosphonate (NH 4C10H21PO3H) (2), ethylenediaminium 1-decylphosphonate 1,5 hydrate (enH2C10H 21PO3·1.5H2O) (3) and calcium 1-decylphosphonate (Ca(C10H21PO3H)2) (4) were prepared and characterized by IR and Raman spectroscopy. The structures of 2 and 3 were determined by single crystal X-ray diffraction analysis. Compound 2 crystallizes in the P1? space group of triclinic system with two molecules in the asymmetric unit cell whereas compound 3 crystallizes in C2/c space group of monoclinic system with four molecules in the unit cell and both exhibit layered supramolecular structures generated by ionic interaction, H-bonding and alkyl chain interdigitation in the case of 3. The FT-IR and Raman spectra have been assigned in the range 4000-500 cm-1 for all compounds, and reveal the trans conformation of alkane chain in all compounds.

Novel phosphorus containing compounds are described, as well as methods for the preparation and pharmaceutical composition of same, which are useful in preventing the intestinal absorption of cholesterol and thus are useful in the treatment of hypercholesterolemia and atherosclerosis.
Phosphonate Complexes. Part 6. Influence of Steric Effects, Solvation, and Chelation on Stability

The interaction of some phosphonic acids RPO(OH)2, chosen to introduce different controlling factors (R=But, cyclo-C6H11, pH, n-C10H21, Me2NCMe2, CH2SEt, CH2CH2CO2(-)), with Ca(II) and Cu(II) has been investigated by potentiometry at 25 deg C, I=0.1 mol dm-3 (K).The selection of the species and the refinement of the stability constants illustrates the applicability of a new version of the program MUCOMP.Examination of linear free-energy plots indicates that factors other than polar effects are of significance, i.e. chelate formation with the potentially bidentate ligands and particularly solvation effects which preferentially stabilize the complexes of α- branched-chain phosphonates.Other features (steric hindrance, predominance of some microscopic forms) are discussed.
