Hydrogen-bonding network of N,N'-bis­[2-(tert-butyl­dimethyl­siloxy)­ethyl]­ethyl­ene­di­ammonium dichloride

Abstract: The title salt, C18H46N2O2Si22+·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.

Formula: C18H46N2O2Si22+·2Cl-
