Bond-valence parameters for characterizing O–H⋯O hydrogen bonds in hydrated borates

Recent Developments in the Methods and Applications of the Bond Valence Model

“…They(64) compare the bond valences calculated using eqs 66 and 67 with similar equations derived from their golden mean model, as well as with others reported in the literature. Because X-ray diffraction gives shorter O−H bonds than neutron diffraction, eqs 68 and 69 give smaller valences for the donor bonds than other parameter sets, but they also give significantly larger valences for the weak bonds.…”

Synthesis, growth and characterization of strontium bis (hydrogen l-malate) hexahydrate bulk single crystal: A promising semi-organic nonlinear optical material

“…According to the the Phillips-Van Vechten-Levine-Xue bond theory [9], constituent chemical bonds of the single crystal determine its NLO responses. Semi-organic materials structurally involve one or more kinds of hydrogen bonds, which have been identified as one of the NLO functional bonds [6,10]. Therefore we may have more chances to find new promising NLO single crystals in the semi-organic area.…”
