Structural Reinvestigation of Ammonium Hypophosphite: Was Dihydrogen Bonding Observed Long Ago?: Structural Reinvestigation of Ammonium Hypophosphite: Was Dihydrogen Bonding Observed Long Ago?. Marincean, Simona; Custelcean, Radu; Stein, Robin S.; Jackson, James E. (Department of Chemistry, Michigan State University, East Lansing, MI 48824-1322, USA). Inorganic Chemistry, 44(1), 45-48 (English) 2005 American Chemical Society. CODEN: INOCAJ. ISSN: 0020-1669. DOCUMENT TYPE: Journal CA Section: 65 (General Physical Chemistry) The past decade has seen the explosive emergence of "dihydrogen bonds", interactions between the electrons of M-H s-bonds, where M is less electroneg. than H (M = Al, B, Ga, Ir, Mo, Mn, Os, Re, Ru, W) and traditional proton donors. But 70 years ago, such an interaction was proposed by Zachariasen and Mooney [J. Chem. Phys. 1934, 2, 34-37] on the basis of their single-crystal X-ray diffraction structure (heavy atoms positions only) of ammonium hypophosphite (NH4H2PO2). We redetd. this structure at high resoln. with a focus on the hydrogen atoms, using a modern diffractometer equipped with a CCD detector. MO calcns. were performed to investigate the charge d. and the bond polarity of the P-H bonds and to assess their potential for participation in dihydrogen bonds. Neither the theory nor the X-ray structure supports the original claim of H×××H interactions in this salt.Except for chemicals metioned above, 7803-65-8 is also used. .
