2-Phenylimidazolium nitrate monohydrate
In the title hydrated mol-ecular salt, C(9)H(9)N(2) (+)·NO(3) (-)·H(2)O, the dihedral angle between the aromatic rings in the cation is 11.09 (8)°. In the crystal, the components are linked into chains propagating in [101] by N-H⋯O and O-H⋯O hydrogen bonds.
متن کامل2-Methylaspartic acid monohydrate
The title compound, C5H9NO4·H2O, is an isomer of the α-amino acid glutamic acid that crystallizes from water in its zwitterionic form as a monohydrate. It is not one of the 20 proteinogenic α-amino acids that are used in living systems and differs from the natural amino acids in that it has an α-methyl group rather than an α-H atom. In the crystal, an O-H⋯O hydrogen bond is present between the ...
متن کامل2-Carboxyanilinium chloride monohydrate
In the mol-ecule of the title compound, C(7)H(8)NO(2) (+)·Cl(-)·H(2)O, an intra-molecular N-H⋯O hydrogen bond results in the formation of a non-planar six-membered ring adopting a flattened boat conformation. In the crystal structure, inter-molecular O-H⋯O and N-H⋯Cl hydrogen bonds link the mol-ecules. There is a C=O⋯π contact between the carbonyl unit and the centroid of the benzene ring. Ther...
متن کامل2-Phenylimidazolium chloride monohydrate
In the title hydrated molecular salt, C(9)H(9)N(2) (+)·Cl(-)·H(2)O, the dihedral angle between the five- and six-membered rings in the cation is 18.00 (2)°. O-H⋯Cl, N-H⋯O and N-H⋯Cl hrdrogen-bonding inter-actions are present in the crystal structure.
متن کاملPotassium 2-iodobenzenesulfonate monohydrate
In the crystal structure of the title compound, K(+)·C(6)H(4)IO(3)S(-)·H(2)O, the potasium cation is 2.693 (3)-2.933 (3) Å from the sulfonate and water O atoms (including symmetry-related atoms) and forms a two-dimensional sheet-like structure in the bc plane, with the iodo-benzene rings protruding above and below. The water mol-ecule of crystallization is hydrogen-bonded to sulfonate O atoms w...
