چکیده
The title compound, C(6)H(8)NO(3)P, is isostructural with p-arsanilic acid. It exists as the zwitterion H(3)N(+)C(6)H(4)PO(3)H(-). In the crystal, mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen-bond bridges, giving a three-dimensional network structure. The strongest hydrogen bonds are formed between adjacent PO(3)H groups with O⋯O distances of 2.577 (2) Å.

متن کاملUnderstanding Hydrogen Adsorption in MIL-47-M (M = V and Fe) through Density Functional Theory
The present paper aims to investigate the role of open metal site metal-organic frameworks (MOFs) on hydrogen adsorptivity using periodic boundary condition (PBC) density functional theory (DFT). Hence, MIL-47-M (M = V and Fe) were selected and one hydrogen molecule adsorptivity was calculated in different orientations on them. Four different chemical sites were identified in every cluster sect...
متن کاملCrystal structure of 2,5-dimethylanilinium hydrogen maleate
The crystal structure of the title salt, C8H12N(+)·C4H3O4 (-), consists of a 2,5-di-methyl-anilinium cation and an hydrogen maleate anion. In the anion, a strong intra-molecular O-H⋯O hydrogen bond is observed, leading to an S(7) graph-set motif. In the crystal, the cations and anions pack in alternating layers parallel to (001). The ammonium group undergoes inter-molecular N-H⋯O hydrogen-bondi...
