چکیده
The reaction of 3,3,3-tris-(dimethyl-amino)-1-phenyl-prop-1-yne with bromine in pentane yields the title compound, C(13)H(17)N(2) (+)·Br(-). The acetyl-enic bond distance [1.197 (2) Å] is consistent with a C C triple bond. The amidinium C=N bonds [1.325 (2) and 1.330 (2) Å] have double-bond character and the positive charge is delocalized between the two dimethyl-amino groups.
