Dissolving lithium chloride and aluminium chloride in boiling para- or meta-xylene and keeping the colourless solution at room temperature led to crystal growth of a new modification of lithium tetra-chlorido-aluminate, LiAlCl4, which represents a second modification (oP12, Pmn21) of the ternary salt besides the long known monoclinic form [LiAlCl4(mP24, P21/c); Mairesse et al. (1977 ▸). Cryst. ...

The orientational relaxation dynamics of perylene in the room temperature ionic liquid (RTIL) 1-butyl-3-methylimidazolium bis(trifluoromethyl)sulfonyl imide were studied as a function of lithium ion concentration. Perylene is nonpolar and locates in the alkyl regions of the RTIL. The lithium cation was added as lithium bis(trifluoromethyl)sulfonyl imide, so the addition of Li(+) did not change ...

A simple and efficient method for the synthesis of quinolines and polycyclic quinolines using Li+ modified nanoporous Na+-montmorillonite is described. This new nanocatalyst proceeds via Friedlander annulation under solvent-free conditions. It describes our observations about a trend of catalytic activity of Lithium cation in nanoporous Na+-montmorillonite. In this study, several types of 1,3-d...

Abstract Investigations on the effect of single or double A-site cation engineering photovoltaic performance bismuth perovskite-inspired materials (A 3 Bi 2 I 9 ) are rare. Herein, we report novel single- and double-cation based developed by (1) completely replacing CH NH + (methylammonium, MA in with various organic cations such as CH(NH (formamidinium, FA ), (CH (dimethylammonium, DMA C(NH (g...

A solid solution was found to exist in the quaternary Li(2)O-MgO-V(2)O(5)-MoO(3) system between the two phases Mg(2.5)VMoO(8) and Li(2)Mg(2)(MoO(4))(3). Both Mg(2.5)VMoO(8) and Li(2)Mg(2)(MoO(4))(3) are isostructural with the mineral lyonsite, and substitution according to the formula square(1/4-x/6)Li(4x/3)Mg(15/4-7x/6)V(3/2-x)Mo(3/2+x)O(12) (0 < or = x < or = 1.5, where square denotes a catio...

The asymmetric unit of the title compound, (C(23)H(33)N(2))[Li(C(32)H(16)N(8))]·0.5C(3)H(6)O·H(2)O, consists of two symmetry-unrelated lithium phthalocyanine (LiPc(-)) half-anions, centered at (1,0,0) and (0,,0), respectively, the bis-(adamant-yl)imidazolium cation (BAI(+)), occupying a general site, an acetone mol-ecule, disordered about the inversion centre at (0, , ) and a water mol-ecule at...

Formation constants for complexion between alkali metal cations and the crown ether 18C6 in the solvent 2-cyanopyridine at 3OoC were determined from conductance measurements. The method allows for precise determination of these formation constants up to values of K around 10" mol-' dm3. The method also f. permits accurate evaluation of association equilibrium constants between the complex speci...

background: lithium has been the treatment of choice for bipolar disorder (bd) for many years. although erectile dysfunction is a known adverse effect of this drug, the mechanism of action by which lithium affects erectile function is still unknown. objective: the aim was to investigate the possible involvement of nitric oxide (no) in modulatory effect of lithium on penile erection (pe). we fur...

[structure: see text] A new type of donor-spacer-acceptor podand system has been synthesized and proved as an efficient dual channel fluorosensor for Li+, Mg2+, and Ca2+. The known ability for the N-oxide function to bind Lewis acids is the key step in the appearance of a new emitting charge-transfer (CT) excited state. The occurrence of this CT state for alkaline earth (Mg2+ and Ca2+) and not ...

Available evidence suggests that Mg2+ ions are involved in reactions catalyzed by hammerhead ribozymes. However, the activity in the presence of exclusively monovalent ions led us to question whether divalent metal ions really function as catalysts when they are present. We investigated ribozyme activity in the presence of high levels of Mg2+ ions and the effects of Li+ ions in promoting ribozy...
