The crystal structure of the title compound, C(12)H(17)BrNO(+)·Cl(-), is stabilized by N-H⋯Cl and C-H⋯O hydrogen bonds, forming a three-dimensional network. The inter-actions framework is completed by C-H⋯π contacts between a methyl-ene group and the benzene ring of a symmetry-related mol-ecule.

In the crystal of the title compound, (C(7)H(10)NO)(4)[BiCl(6)]Cl·H(2)O, the Bi(III) cation is located on an inversion center and coordinated by six Cl(-) anions in a slightly distorted octa-hedral geometry; the uncoordinated Cl(-) anion and lattice water mol-ecule are located on a twofold rotation axis. Two independent 4-meth-oxy-anilinium cations are linked to the Bi complex, the uncoordinate...

The title compound, C(8)H(11)N(2)O(3) (+)·Cl(-), was synthesized as an inter-mediate in the development of a new sugar sensor. The structure displays N-H⋯Cl and O-H⋯O hydrogen bonding, as well as weak O-H⋯Cl inter-actions and π-π stacking (3.298 Å). There are two formula units in the asymmetric unit.

The hydrazinium residue in the cation of the title salt, C(6)H(10)N(3)O(2)S(+)·Cl(-), is twisted out of the plane of the benzene ring to which it is attached [N-N-C-C torsion angle = 25.9 (2)°] and the amino group is almost perpendicular to the benzene ring [N-S-C-C torsion angle = 88.71 (16)°]. In the crystal, the cations are linked by N-H⋯O hydrogen bonds and π-π inter-actions [ring centroid ...

In the title salt hydrate, C(11)H(12)ClN(2) (+)·Cl(-)·H(2)O, the quinolin-ium core is essentially planar (r.m.s. deviation = 0.027 Å) with the chloro-ethyl side chain being almost orthogonal to the core [C-N-C-C torsion angle = -80.0 (3)°]. In the crystal packing, the water mol-ecule bridges three species, forming donor inter-actions to two chloride anions and accepting a hydrogen bond from the...

In the title mol-ecular salt, C(11)H(17)N(2) (+)·Cl(-), the piperazin-1-ium ring adopts a chair conformation with the aromatic ring in a pseudo-equatorial orientation. The dihedral angle between the benzene ring and the mean plane of the piperazin-1-ium ring is 51.22 (6)°. In the crystal, N-H⋯Cl hydrogen bonds link the mol-ecules into chains propagating in [100]. Weak C-H⋯π inter-actions also o...

In the title hydrated salt, C(15)H(11)Br(2)N(2) (+)·Cl(-)·2H(2)O, the complete imidazolium cation is generated by a crystallographic twofold axis, with one C atom lying on the axis. The chloride ion and both water mol-ecules of crystallization also lie on a crystallographic twofold axis of symmetry. The cation is non-planar, the dihedral angle formed between the central imidazolium and benzene ...

In the title compound, C19H21ClN2O2, the aromatic rings are approximately perpendicular to each other, subtending a dihedral angle of 87.7 (1)°. In the crystal, the 4-nitro-phenyl groups of pairs of neighbouring mol-ecules are parallel and oriented head-to-tail with a ring centroid-centroid distance of 3.9247 (12) Å, leading to a π-π inter-action between the pair. The faces of each phenyl ring ...
