Intercalation of 1-Alkanols and 1,ω-Alkanediols into NbOPO4and NbOAsO4

“…sufficient amounts of the guest molecules, the chains in the intercalate possess the all-trans configuration (1,18) and their axes form either an acute angle (usually 55-60°) (11,16) or a right angle (1,13,14,17) with the host layers. The arrangement of the guest molecules in the interlayer space of the host is most often bimolecular (10,14,17).…”

Triclinic lattice constants of saturated mono-acid triglycerides

“…No kink effects have been established, however, in the very densely packed triclinic chain arrangements. Previous discussions of such lattice defects referred exclusively to the less dense chain packings of the orthorhombic modifications of paraffins (Blasenbrey & Pechhold, 1967), polyethylene (Pechhold, 1968), triglycerides (Precht, Frede & Greiff, 1978), or to the system tetradecylammonium beidellite/ tetradecanol (Lagaly, Fitz & Weiss, 1975). In all possible configurations fl(4,1,0) and fl(4,-1,1) structures with periodicities in the area of terminal groups of fatty acids ... NL~ N... and ... NNN... and relative chain positions 3:3 and l:l would provide a satisfactory interpretation of the measured long spacings.…”

Intercalates of Vanadyl Phosphate with Branched Alcohols

“…A number of papers have reported attempts to find the principles governing the structure arrangements of unbranched aliphatic molecules with terminal functional groups during their intercalation into various host structures 1,2. With this aim the intercalations of, for example, aliphatic alcohols, diols and amines into some natural silicates,3,4 vanadyl phosphate and sulfate,5−8 α‐ and γ‐ Zr(HPO 4 ) 2 ·H 2 O,9,10 and other similar hosts were investigated.…”
