The cation of the title compound, C(7)H(13)ClN(+)·Cl(-), forms a linear hydrogen bond to the chloride anion. The cation is disordered about a mirror plane.
The low-temperature structure of the title compound, C(4)H(8)N(2)O, is ordered, whereas the central methyl-ene groups is disordered in the reported room-temperature structure. The molecule lies across a mirror plane; adjacent mol-ecules are linked by an N-H⋯O hydrogen bond into a chain.
The hydroxyl group in each of the two independent mol-ecules of the title compound, C(7)H(5)NO(4), participates in two O-H⋯O hydrogen bonds, viz. one intra-molecular bond to the nitro group and one inter-molecular bond to the aldehyde group of the same mol-ecule in the next unit, resulting in a linear chain structure. The dihedral angle between the aromatic… (More)
THE TITLE COMPOUND (SYSTEMATIC NAME 3,5-dichloro-2-hydroxy-benzaldehyde), C(7)H(4)Cl(2)O(2), crystallizes as discrete mol-ecules, the conformation of which may be influenced by an intra-molecular hydr-oxy-carbonyl O-H⋯O hydrogen bond.
