Hydrogen Bonding in Solids: Methods of Molecular Structure Determination

Transition metal bifluorides

“…Driven by the isomorphism between molybdenum and tungsten, and considering the similarities of the reaction conditions and the obtained X-ray diffraction data with the Mo-FHF species described above, the complex formula was therefore re-examined. It was later shown that the experimental data were in excellent accord with the reformulation of the complex to the bifluoride species [WF(H) 2 M a n u s c r i p t…”

“…Hydrogen bond interactions are one of the most important intra-and intermolecular interactions in chemistry [1][2][3][4][5][6][7]. Understanding these interactions has been the driving force behind numerous studies, mostly revolving around non-metal systems.…”

Structure and absolute configuration of the potassium thiocyanate complex of 1,4,7,10,13-pentaoxa-16-thiacyclooctadecane

“…Thus, neighboring heteroatoms are in contact with one another. between a H atom and an orbital containing nonbonded electrons on O (Hamilton & Ibers, 1968). The same type of interaction involving a polyether, along with its implications, has been discussed previously (Goldberg, 1975).…”

Structure of tetraethylammonium bromide–succinimide (1/2)

“…The resulting Br--.H distances are 2.44 and 2.43/~, more than 0.2/~ shorter than the sum of the van der Waals radii for Br and H (3.15/~) (Chemistry Data Book, 1982). Thus, the bromide ion is hydrogen bonded to the succinimide molecules (Hamilton & Ibers, 1968). This is also indicated by the sum of the Br-ionic radius (1.95/~), the covalent radius of N (0.74/~) and the covalent diameter of H (0.74A), which is 3.43 A (Chemistry Data Book, 1982) …”
