Abstract
Vanadyl(1V) phosphite, VOHP03.1.5H20, was synthesized by reduction of V205 in refluxing alcohol solutions (ethyl, isopropyl, and isobutyl alcohols) with subsequent addition of H3P03. X-ray diffraction suggests an orthorhombic space group. Magnetic susceptibility data indicate the presence of exchange coupled vanadyl dimers associated with face-shared vanadyl octahedra similar to vanadyl hydrogen phosphate hemihydrate, VOHP04.0.5HzO. Vanadyl(IV) phosphite is a layered solid with an interlayer spacing of 7.27 A. n-Alkylamines intercalated into the layered structure as siqgle or double layers depending on the amineto-host ratio, and the interlayer spacings, d (A), increased linearly with the carbon number, n,, as d = 7.72 + 0.85nC (monolayers), and d = 6.49 + 1.82~~~ (bilayers).
