چکیده
The imino-diacetic acid component of the title salt, C(4)H(8)NO(4) (+)·C(7)H(7)SO(3) (-), is protonated at the N atom. The cation uses the ammonium group to form hydrogen bonds to the O atoms of two adjacent sulfonate groups. In addition, the carboxylic acid portions of the cation form hydrogen bonds to the sulfonate groups. The hydrogen-bonding inter-actions give rise to a layer structure.

The crystal structure of the title compound, C(7)H(10)N(+)·C(7)H(7)O(3)S(-), displays strong N-H⋯O and N-H⋯S hydrogen bonding between the ammonium group and the p-toluene-sulfonate anion, linking the cations and anions into chains along the b axis.

In the title compound, C(7)H(9)N(2)O(4) (+)·I(3) (-)·C(7)H(8)N(2)O(4), the two imidazolium units are hydrogen bonded through the carboxyl groups. The units are further linked via inter-molecular O-H⋯O hydrogen bonding, resulting in a one-dimensional ladder-type structure. As a result, the two carb-oxy groups of each imidazolium unit adopt a cis configuration with respect to the imidazolium ring.

In the crystal of the title compound, C(8)H(10)NO(2) (+)·Cl(-), alternating layers of hydro-phobic and hydro-philic zones stack along the c axis. The chloride anions are sandwiched between the 4-(carboxy-meth-yl)anilinium layers, forming inter-molecular O-H⋯Cl and N-H⋯Cl hydrogen bonds with the ammonium and carboxyl groups of the cations. In addition, inter-molecular N-H⋯O and weak C-H⋯O and C-...

In the crystal structure of the title salt, C(3)H(10)N(+)·C(7)H(7)O(3)S(-), N-H⋯O hydrogen bonds involving the ammonium groups of the cations and the sulfonate O atoms result in the formation of a three-dimensional network.
متن کاملDiscrimination of methylammonium from organic ammonium ions using ion-selective electrodes based on calix[4]arene-crown-6 conjugates.
Calix[4]-bis-2,3-naphtho-crown-6 can be used to discriminate between methylammonium and other organic ammonium ions. An electrode based on this ionophore, potassium tetrakis(p-chlorophenyl)borate (20 mol% relative to the ionophore) as an ionic additive and bis(2-ethylhexyl) sebacate as a solvent mediator in a poly(vinyl chloride) membrane matrix, displayed higher selectivity for methylammonium ...
