Hexaethylguanidinium chloride

The title compound, C13H30N3+center dot Cl-, is a phase-transfer catalyst. The geometry at the central C atom of the guanidinium cation, which lies on a twofold rotation axis, is almost ideal trigonal planar, with N-C-N angles of 119.8 (2) and 120.08 (11)degrees. The chloride anion also lies on a twofold rotation axis.
