The ternary chloride Na3MoCl6 is obtained as red crystals from a disproportionation reaction of molybdenum dichloride, {Mo6}Cl12, in an acidic NaCl/AlCl3 melt at 350°C. The crystal structure (trigonal, P-31c, a = 687.1(1), c = 1225.3(2) pm, Z = 2, V = 501,0(1) 10 pm) is that of Na3CrCl6: within a hexagonal closest-packing of chloride ions two thirds of the octahedral voids are filled between th...

The asymmetric unit of the title compound, C(2)H(9)N(5) (2+)·2Cl(-), is composed of one diprotonated biguanidinium cation and two chloride anions. The diprotonated cation consists of two planar halves twisted by 36.42 (6)°. The ions are associated in the crystal structure by extensive hydrogen bonding into a three-dimensional network; the diprotonated biguanidinium cation is hydrogen bonded to ...

Ionic activities of sodium, potassium, and chloride in serums of 26 hospitalized patients were determined with ion-specific electrodes. Comparison of the activities with the corresponding concentrations shows that the two most important parameters influencing the molar activity coefficients of these ions are the water content of serum and the binding between albumin and chloride. Quantitative e...

The thermotransport of divalent Sr, Cd and Mn ions in silver chloride and bromide has been investigated experimentally. A model for the intrinsic contribution to the heat of transport is pro­ posed. This model is used to interpret our experiments, together with other experiments reported in the literature, namely the thermoelectric power of pure silver chloride and bromide, and the thermotransp...

An acid sialidase partially purified from porcine liver was activated by incubation at 37 degrees C under acidic pH. This activation was dependent on pH, time and temperature, but not inhibited by amastatin, an inhibitor of aminopeptidase A, in contrast to the case of human placental sialidase. The effects of inorganic anions on the two sialidases from porcine liver and from human placenta were...

The potassium-chloride co-transporter KCC2, encoded by SLC12A5, plays a fundamental role in fast synaptic inhibition by maintaining a hyperpolarizing gradient for chloride ions. KCC2 dysfunction has been implicated in human epilepsy, but to date, no monogenic KCC2-related epilepsy disorders have been described. Here we show recessive loss-of-function SLC12A5 mutations in patients with a severe ...

In the centrosymmetric dinuclear title compound, [Mn(2)Cl(4)(C(15)H(14)N(4))(2)(H(2)O)(2)], the Mn(II) atom is coordinated by an N,N'-bidentate ligand, a water mol-ecule, a terminal chloride ion and two bridging chloride ions in a distorted MnN(2)OCl(3) octa-hedral geometry. The Mn⋯Mn separation is 3.6563 (9) Å. In the crystal structure, O-H⋯N and O-H⋯Cl hydrogen bonds help to establish the pac...

We demonstrate N-phosphorylation and N-thiophosphorylation of unprotected aminonucleosides in aqueous media. N-Phosphorylations using phosphoric chloride and N-thiophosphorylations using thiophosphoryl chloride were explored as functions of pH using 50-amino-50-deoxyguanosine as substrate. These reagents were compared to phosphodichloridate and thiophosphodichloridate ions, and the methodology ...

The asymmetric unit of the title salt, (C(6)H(14)N)(3)[FeCl(4)]Cl(2), consists of a tetra-hedral tetra-chloro-ferrate anion, three independent 2-methyl-piperidinium cations and two chloride ions. All the piperidine rings adopt chair conformations. In the crystal, the organic cations and the free chloride anions are linked into chains parallel to the a axis by N-H⋯Cl hydrogen bonds.
