The crystal structure of the title compound, C(14)H(15)N(2)O(4) (+)·Cl(-), can be described as being composed of layers containing both cations and anions that are staggered along [010]. Two types of the hydrogen bonds are observed, viz. cation-anion and cation-cation. The chloride anions are acceptors of the strong hydrogen bonds donated by the secondary amine and the hy-droxy groups. The pack...

The Pd(II) atom in the complex cation of the title compound, [PdCl(C(21)H(16)N(4))]Cl, is coordinated by three N atoms derived from the terpyridine ligand and a chloride ion, which define a distorted PdClN(3) square-planar coordination geometry. In the crystal, the presence of N-H⋯Cl hydrogen bonds involving the amino H atom and chloride anions link two cations and two anions into a four-ion ag...

The effects of transport inhibitors on the movements of oxalate and chloride across the isolated short circuited rabbit colon were studied. Net oxalate absorption was shown in this species and was shown to be an energy dependent process as indicated by its sensitivity to 2-4 dinitrophenol (DNP) 10(-4)M. Mucosal addition of 4-acetamido-4-isothiocyano-2,-stilbene-2,2'-disulfonic acid (SITS) 10(-4...

In the title salt, C(16)H(21)N(2)O(+)·Cl(-), the amide group makes a dihedral angle of 24.98 (2)° with respect to the pyridinium ring. In the crystal, both the amide and pyridinium N atoms are involved in N-H⋯Cl hydrogen bonding. Weak inter-molecular C-H⋯Cl and C-H⋯O inter-actions also occur.
