The organic cation in the title compound, C(24)H(32)N(4) (2+)·2Cl(-)·3H(2)O, is situated on an inversion centre. The cations, anions and water mol-ecules are linked via N-H⋯O, N-H⋯Cl, O-H⋯O and O-H⋯Cl hydrogen bonds and C-H⋯π interactions, forming a three-dimensional framework.

Physiological ligands of (sodium-potassium)-dependent adenosine triphosphatase influenced the sensitivity of the enzyme to the inhibitor, ouabain. Phosphorylation of the native enzyme is accelerated by sodium ions, while potassium ions accelerate dephosphorylation. Exposure of the phosphoenzyme to ouabain slowed its turnover and rendered it insensitive to potassium ion. This action of ouabain d...

Sodium salicylate was administered to anesthetized dogs in doses sufficient to produce concentrations in plasma comparable to those common in human salicylate toxicity. Salicylate administration increased the rates of excretion of water, sodium, and chloride in the urine. Salicylate administration also increased the rate of excretion of potassium so that its clearance often exceeded that of cre...

The concentrations of sodium, potassium, magnesium, cal cium, chloride, and phosphate were determined in Ehrlich ascites tumor cells and fluid after 5, 7, 9, and 12 days of growth. Material obtained after the 12th day showed peculiar intra cellular ion patterns, presumably related to the near-terminal condition. Material drawn after 5-9 days of growth represented viable cells. The intracellular...

The title compound, [Ni(2)(C(12)H(12)N(2)O(4)S(3))(H(2)O)(4)]·2C(3)H(7)NO·3H(2)O, is made up of a centrosymmetric, bimetallic complex containing a 24-membered macrocyclic ring, two dimethyl-formamide and three water solvent mol-ecules. The Ni atom adopts a slightly distorted NiO(6) octahedral geometry arising from two O,O-bidentate ligands and two water molecules. There are inter-molecular O-H⋯...

In the title compound, [Cu(C(13)H(8)N(4)O(3))(H(2)O)]·3H(2)O, the complex molecule, except for the aqua ligand, is essentially planar [r.m.s. deviation = 0.034 (2) Å]. The coordination polyhedron of the Cu(2+) cation is a square-pyramid, with the aqua ligand at the apex. The compound exhibits a three-dimensional structure, which is is stabilized by O-H⋯O and O--H⋯N hydrogen bonds and π-π inter-...
