The magnitude of the stability constants (K) for the formation of X3– from X– and X2 (X = Cl, Br, I) in aqueous and nonaqueous solution depends strongly on both X and solvent. Thermodynamic arguments establish that for aqueous solutions this is n

The reactions of indium monohalides, InX with haloforms, CHX3, in 1,4-dioxane (diox), produce the dioxane adducts of dihalogeno–dihalogenomethyl–indium(III), X2In(diox)nCHX2 (X = Cl, Br, n = 1; X = I, n = 2) compounds. The ionic derivative [(C2H5

Complexes of lead(II) of the type Pb(O 2 R) where R is a substituted aromatic group, can be prepared by the direct electrochemical oxidation of a lead anode in a non-aqueous solution of the appropriate substituted catechol, R(OH) 2 . The products, wh

Solutions of I2 + X− (X = Cl, Br, I. NCS) in both water and acetonitrile have been studied by electrospray mass spectrometry in order to identify the anions present. For I2/I−, there is no evidence of the I5− anion proposed earlier to explain d

Laser desorption/ionisation mass spectrometry of the elements sulfur, selenium, tellurium and phosphorus has shown a range of polynuclear ions in both positive and negative ion modes. Three-dimensional topographical surfaces are used to display chang

The bis-1,4-dioxane (diox) adduct of bromomethyl-dibromo-indium(III), Br 2 In(diox) 2 CH 2 Br, reacts with triphenylphosphine oxide, triphenylphosphine sulfide and benzyl sulfide to produce the compounds Br 2 In[OP(C 6 H 5 ) 3 ] 2 CH 2 Br and Br 3 In

The 27Al and 71Ga NMR spectra of mixtures of M2X6 and M2Y6 (M = Al, Ga; X ≠ Y = Cl, Br or I) in benzene are reported. All these systems show rapid inter-halogen exchange, and in some cases stable intermediates M2XnY6 − n can be characterised spec

Germanium powder reacts slowly with 3,5-di-tert-butyl-1,2-benzoquinone (dbbq) in refluxing toluene to give products whose composition depends on the initial mole ratio of the reactants. When Ge ∶ dbbsq = 1 ∶ 2, the solid product is a monoradical

The reaction of InBr with CH2Br2 in 1,4-dioxane or acetonitrile yields the corresponding solvate of Br2InCH2Br, which on reaction with E(C6H5)3 (E=P, As, Sb) gives the indium(III)-Group 15 dimetallo-methane derivatives, Br3InCH2E(C6H5)3. The crystal

Solutions prepared by equibrating solid AlCl3 and benzene have been studied by 27Al NMR spectroscopy. Evidence of hydrolysis of AlCl3 is found, both under nominally anhydrous conditions and in the presence of added H2O. Results are also reported for
