The Stability and Properties of Mn+@ C26-2nBnNn(M= alkaline and earth alkaline metals; n=0, 3) Complexes for Synthesis Application

The structural and electronic properties of C24-2nBn Nn and M@ C24-2nBn Nn (M= alkaline and earth alkaline metals; n=3 and 6) molecules are studied using the Density Functional Theory (DFT). It was found that the most interaction is in M@ C24-2nBn Nn complexes (M=Be, Mg; n=3 and 6). The negative nucleus-independent chemical shifts confirm that C24-2nBn Nn (n=3 and 6) cages exhibit aromatic char...

The effect of alkaline earth metals (Magnesium and Calcium) on Hydrogen storage efficiency of alanate nanopowders

Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...

π Ligands in Alkaline Earth Complexes

Alkaline and alkaline earth metal complexes of dianhydride derivatives of clodronate and their hydrolysis products.

Alkaline and alkaline earth metal complexes of P,P'-diacetyl- (L1(2-)); new P,P'-dipropanoyl- (L2(2-)) and P,P'-dibenzoyl(dichloromethylene)bisphosphonates (L3(2-)) and their hydrolysis products were prepared and characterized using the single-crystal X-ray diffraction technique and spectroscopy, with the intention of studying the hydrolysis and coordinating properties of these potential prodru...
