Synthesis and Structure of Dicyclohexylammonium Tri‐ tert ‐pentoxysilanethiolate and 5‐Aminopentylammonium Tri‐ tert ‐pentoxysilanethiolate

Tri– tert –pentoxysilanethiol, (EtMe 2 CO) 3 SiSH, reacts with dicyclohexylamine and 1,5–diaminopentane yielding ion‐quadruples connected by hydrogen bonds: [{(C 6 H 11 ) 2 NH 2 } + {(EtMe 2 CO) 3 SiS} − ] 2 ( 1 ) and [{H 2 N–C 5 H 10 –NH 3 } + {(EtMe 2 CO) 3 SiS} − ] 2 ( 2 ). The compounds were characterized by X–ray diffraction, elemental analysis, IR and NMR. Both compounds form dimers, composed of two thiolate anions and two ammonium cations. The dimers have a central core of eight–membered rings built due to the formation of four charge–assisted N + –H··· − S–hydrogen bonds. Additional N + –H···N hydrogen bonds are found in the case of 2 , linking the dimers into infinite two–dimensional sheets.
