In the crystal structure of the title salt, C(10)H(16)N(+)·ClO(4) (-), the 4-butyl-anilinium cation is mirror symmetric, the butyl C atoms and anilinium N atom and 1,4-position C atoms of the benzene ring being located on the mirror plane; the perchlorate anion is also mirror symmetric, with two O atoms and one Cl atom lying on the mirror plane. Trifurcated N-H⋯O hydrogen bonding is observed be...

In the title complex, [Zn(C(7)H(6)NO(2))(2)(C(10)H(8)N(2))], the Zn(II) cation is coordinated by two amino-benzoate anions and one 2,2'-bipyridine ligand in a distorted trigonal-bipyramidal geometry. The carboxyl-ate group of one aminobenzoate anion coordinates to the Zn(II) cation in a monodentate manner, whereas the carboxyl-ate group of the other amino-benzoate anion chelates the Zn cation w...

The asymmetric unit of the title compound, 2C(3)H(10)N(+)·C(10)H(6)S(2)O(6) (2-), contains a half-anion, which is completed by inversion symmetry, and one cation. The cations and anions are associated via strong N-H⋯O(sulfonate) hydrogen-bonding inter-actions, forming cation-anion-cation groups. Secondary inter-actions such as C-H(ammonium)⋯O(sulf-on-ate) and van der Waals inter-actions link th...

In the title compound, C(16)H(18)NO(2) (+)·C(7)H(7)O(3)S(-)·H(2)O, the dihedral angle between the pyridyl and benzene rings of the pyridinium cation is 0.2 (1)°. The benzene ring of the tosyl-ate anion makes a dihedral angle of 4.8 (2)° with the best mean plane of the pyridinium cation. The pyridinium cation and the tosyl-ate anion are hydrogen bonded to the water mol-ecule, and the crystal pac...

In the crystal of the title compound, (C4H12N)[FeCl4]·C12H24O6, the butan-1-aminium cation and the tetra-chloridoferrate(III) anion have m symmetry: in the cation, the non-H atoms are located on the mirror plane and in the anion, the Fe(III) atom and two Cl atoms are located on the mirror plane. The 18-crown-6 mol-ecule also has m symmetry, with two O atoms located on the mirror plane. The buta...

The title compound, NH(4) (+)·C(6)H(10)NS(2) (-), is composed of an ammonium cation and a piperidine-1-carbodithio-ate anion which exhibits positional disorder. The atoms of the ring have a structural disorder and they are divided into two sites, with occupancy factors of 0.584 and 0.426.. In the crystal, the cation and anion are linked by N-H⋯S hydrogen bonds to form an infinite two-dimensiona...

Anion binding by neutral hosts in organic solvents can be inhibited by the presence of alkali metal cations. The binding inhibition is due to salt ion-pairing which increases in the order Cs(+) < K(+) < Na(+). The binding inhibition can be reversed by using heteroditopic hosts that simultaneously bind both the metal cation and the anion. The largest cation-induced enhancements are observed with...

Acidifying diets (either by addition of anionic salts or mineral acids) are commonly used in the United States to prevent milk fever in dairy cattle. The ability of different diets to cause acidification of the cow can be explained by dietary cation-anion difference (anion-cation balance, dietary electrolyte balance, strong ion difference). The DCAD of diets can be manipulated with relative eas...

In the title complex, [Mn(CHO(2))(C(12)H(8)N(2))(2)]ClO(4), the Mn(II) cation is chelated by two 1,10-phenanthroline (phen) ligands and one formate anion in a distorted MnN(4)O(2) octa-hedral geometry. The two phen planes are oriented at a dihedral angle of 57.48 (11)°. The perchlorate anion links with the Mn complex cation via weak C-H⋯O hydrogen bonding.

In the title salt, C(7)H(11)N(2) (+)·Br(3) (-), the cation and the near-linear anion [Br-Br-Br = 179.41 (8)°] both show whole-mol-ecule disorder about crystallographic twofold rotation axes. The cation is weakly hydrogen-bonded to the anion by an N-H⋯Br inter-action. The crystal studied was found to be a racemic twin, with a twin component of nearly 50%.
