Anhydrous indium trichloride reacts with [2-(Ph2P)C6H4]2PPh (TP) in the molar ratio 2:1 to give an ionic complex [(TP)InCl2]+ InCLin almost quantitative yield. The structure of the product has been determined by a single crystal X-ray diffraction study. In the cation the TP molecule acts only as a bidentate ligand via its two terminal phosphorus atoms [In-Pl 2.5956(8), In-P2 2.5799o(7) A], Alth...

We consider the inequality $f \geqslant f\star f$ for real integrable functions on $d$ dimensional Euclidean space where $f\star denotes convolution of $f$ with itself. show that all such are non-negative, which is not case same in $L^p$ any $1 < p \leqslant 2$, defined. also solutions satisfy $\int f(x){\rm d}x \tfrac12$. Moreover, if = \tfrac12$, then must decay fairly slowly: |x| \infty$, an...

The sheltered environment of the Algares +30 level adit (underground mine gallery) contributes to preservation secondary water-soluble minerals formed on tunnel walls. massive sulphide and related stockwork zone are hosted by Mine Tuff volcanic unit exposed in walls gallery, showing intense oxidation hydrothermal alteration. Minerals from halotrichite group were identified efflorescent salts, t...
