Abstract:
In the title salt, C21H17 +·ClO4 -, two hydrogen bonds from the tropylium moiety and the vinyl group connect the cation with oxygen atoms of the perchlorate anion. The perchlorate anion is surrounded by three tropylium cations. The tropylium rings of the cations, which are related via a C2 axis, are mostly parallel with a short distance between the centroids.
