Abstract:
The title salt, C18H46N2O2Si2(2+)·2Cl(-), has been synthesized by reaction of N,N'-bis(2-hydroxyethyl)ethylenediamine with tert-butyldimethylsilyl chloride. The zigzag backbone dication is located across an inversion centre and the two chloride anions are related by inversion symmetry. The ionic components form a supramolecular two-dimensional network via N-H···Cl hydrogen bonding, which is responsible for the high melting point compared with the oily compound N,N'-bis[2-(tert-butyldimethylsiloxy)ethyl]ethylenediamine.

Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared.
Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...
