title: N-[Bis(dimethyl-amino)-methyl-idene]-2-[(triphenyl-meth-yl)sulfan-yl]ethanaminium hexa-fluoro-phosphate.
abstract: The mol-ecular structure of the title compound, C(26)H(32)N(3)S(+)·PF(6) (-), shows a protonated guanidyl group bridged by an ethyl-ene linker with a tritylsulfanyl unit. The guanidinium (gua) unit displays charge delocalization over the three N-C(gua) bonds. The N-C-C-S group shows a folded nonplanar conformation with a torsion angle of 158.4 (1)°. In the crystal, the cation and anion are linked by an N-H⋯F inter-action.
