The X-ray structure of the title compound has been determined for first time. Its molecular is in good agreement with those previously similar benzyl halides and angles between ring–Cl bonds adjacent molecules show values an early Zeeman quadrupole spectroscopy study.

In the title molecular salt, C(9)H(18)NO(+)·Cl(-), the morpholine ring adopts a chair conformation. In the crystal structure, intra-molecular C-H⋯Cl bonds occur and inter-molecular C-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules.

In the title compound, C(11)H(10)N(3)O(4)S(+)·Cl(-), the benzene ring makes an angle of 89.2 (1)° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 15.7 (1)°. The crystal structure is stabilized by N-H⋯Cl hydrogen bonds.

In the title compound, C(7)H(16)NO(2) (+)·Cl(-), the asymmetric unit consists of two cation-anion pairs, in which the ion pairs are inter-connected by weak C-H⋯Cl hydrogen bonds. Each cation forms a network of weak C-H⋯Cl hydrogen bonds to surrounding chloride ions. The morpholine ring is in a chair conformation. The crystal structure is consolidated by O-H⋯Cl, C-H⋯Cl and C-H⋯O inter-molecular ...
