Interplay between dihydrogen and alkali–halogen bonds: Is there some covalency upon complexation of ternary systems?
In this study, a theoretical investigation of traditional dihydrogen bonds and novel alkali–halogen bonds was performed in relation to the formation of NaH⋯HCF3 and NaH⋯HCCl3 binary and NaH⋯2(HCF3) and NaH⋯2(HCCl3) ternary ...
Effect of beryllium bonds on the keto–enol tautomerism of formamide derivatives: a subtle basicity–acidity balance
The effects of the association of BeH2 to formamide derivatives have been investigated through the use of G4 high-level ab initio calculations. The association takes place preferentially at the carbonyl group of the amide ...

Estrutura cristalina e refinamento de deformação em sais de ácido piromelítico
(Universidade Federal de Minas GeraisUFMG, 2012-02-17)
Four organic salts derived of 1,2,4,5-benzenetetracarboxylic acid (pyromellitic acid) have been synthesized: bis(3-aminopyridinium) 1,4-dihydrogen 1,2,4,5- benzenetetracarboxylate tetrahydrate (1), bis(3-carboxyphenilammonium) ...
Effect of methacryloyloxydecyl dihydrogen phosphate–containing silane and adhesive used alone or in combination on the bond strength and chemical interaction with zirconia ceramics under thermal aging
(Operative Dentistry Inc, Indiana Univ School Dentistry, 2020)
Objectives: To evaluate the effect of a methacryloyloxydecyl dihydrogen phosphate (MDP)-containing silane coupling agent and universal adhesive, used alone or in combination, on the microshear bond strength (mu SBS) to ...
Bis[(dihydrogen pyrophosphatoκ-2 O,O′)(2,2′: 6′,2″-terpyridine-κ3 N,N′,N″)copper(II) ] 4.5-hydrate
(Wiley Blackwell Publishing, Inc, 2011-05)
The title copper complex, [Cu(H2P2O 7)(C15H11N3)]2·4. 5H2O, consists of two very similar independent Cu(Tpy)H 2P2O7 monomeric units (Tpy is 2,2′:6′,2″-terpyridine) plus four and a half water mol-ecules of hydration, some ...
Hydrogenation of Multiple Bonds by Geminal Aminoborane-Based Frustrated Lewis Pairs
The hydrogenation reaction of multiple bonds that is mediated by geminal aminoborane-based frustrated Lewis pairs (FLPs) has been explored by means of density functional theory calculations. It was found that the release ...
Effect of silica coating combined to a MDP-based primer on the resin bond to Y-TZP ceramic
The aim of this study was to evaluate the influence of silica coating and 10-methacryloyloxydecyl dihydrogen phosphate (MDP)-based primer applications upon the bonding durability of a MDP-based resin cement to a yttrium ...
