The title compound, C33H29N, was obtained by the reaction of 9-chloro­methyl­anthracene and n-propyl­amine. Two anthra­cenyl­methyl units are linked to the N atom of n-propyl­amine and the dihedral angle between the two anthracene systems is 64.3 (2)°.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Disorder prsent in n-Pr group, modelled over 2 sites with isotropic adps, distance restraints and occupancies 0.621 (14) and 0.379 (14).
