The cation of the title compound, C(14)H(15)N(2)O(2) (+)·Cl(-), comprises two almost ideally planar systems, 3-nitro-phenyl (r.m.s. deviation = 0.0117 Å) and 4-methyl-phenyl (r.m.s. deviation = 0.238 Å), separated by the central C-N bond, and with their mean planes inclined to one another by 61.36 (5)°. In the crystal, hydrogen-bonded chains running along [001] are generated by connecting neigh...

The title compound, (C(7)H(10)N)(3)[SbCl(5)]Cl·H(2)O, consists of 4-methyl-anilinium cations, Cl(-) and [SbCl(5)](2-) anions and water mol-ecules. The five Cl atoms bound to Sb [Sb-Cl = 2.4043 (9)-2.6262 (11) Å] form a square-pyramidal coordination environment. In addition, two [SbCl(5)](2-) anions related by an inversion center are joined by Sb⋯Cl inter-actions [Sb⋯Cl = 3.7273 (14) Å] into an ...

The hydro-chloride salt of isonicotinamide, C6H7N2O(+)·Cl(-), has been synthesized from a dilute solution of hydro-chloric acid in aceto-nitrile. The compound displays monoclinic symmetry (space group C2/c) at 150 K, similar to the related hydro-chloride salt of nicotinamide. The asymmetric unit contains one protonated isonicotinamide mol-ecule and a chloride anion. An array of hydrogen-bonding...

In the cation of the title compound, C(9)H(12)NO(2) (+)·Cl(-), the dihedral angle between the 2-oxoethanaminium N-C-C(=O)- plane [maximum deviation = 0.0148 (12) Å] and the benzene ring is 7.98 (8)°. The meth-oxy group is approximately in-plane with the benzene ring, with a C-O-C-C torsion angle of -2.91 (18)°. In the crystal, the cations and chloride anions are connected by N-H⋯Cl and C-H⋯Cl h...

In the title compound, C(16)H(21)N(2)O(+)·Cl(-), the amide group makes a dihedral angle of 25.9 (1)° with respect to the pyridine ring. In the crystal, inter-molecular N-H⋯Cl bonds and weak C-H⋯Cl and C-H⋯O contacts link the cations and the anions into layers parallel to the ac plane. The layers are packed along [010] by hydro-phobic inter-actions between adamantane units.

The title compound, C(8)H(11)FN(5) (+)·Cl(-), crystallized with a monoprotonated 1-(4-fluoro-phen-yl)biguanidinium cation and a chloride anion in the asymmetric unit. The biguanidium group is not planar [dihedral angle between the two CN(3) groups = 52.0 (1)°] and is rotated with respect to the phenyl group [τ = 54.3 (3)°]. In the crystal, N-H⋯N hydrogen-bonded centrosymmetric dimers are connec...
