CH···O hydrogen bonds (HBs) are ubiquituous in silica zeolite crystals hosting cationic Organic Structure Directing agents (OSDAs). This new finding is notably supported by a correlation between exptl. C-O distances and COSi angles’ distributions of two series of 19 and 11 available structures. The correlation enables to asses the directionality of the CH… O intermol. interactions and to extrapolate a geometrical model for the hydrogen bonded moeities. DFT-D3 calculations on representative structures further confirmed the presence of these HBs and their geometry on the basis of H-O distances, CHO angles and electron d. The reported insights demonstrate also the particularities of these intermol. interactions in terms of charge distribution and electrostatic potentials. Further, multiple hydrogen bonding is evidenced between OSDAs and zeolites’ channels and cages, opening new perspectives in the study of zeolite-OSDA host-guest interactions. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Product Details of 75-57-0).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available. Alkyl chlorides readily undergo attack by nucleophiles.Product Details of 75-57-0
