摘要：

A platy specimen of n-C24H50 grown from n-dodecane has been found to be a twin. Bragg reflections from the two twins overlap extensively and a cyclic procedure was used to correct the observed intensities for mutual overlapping. The resulting data could only be refined isotropically to R = 0.23, but the molecule is not overly distorted. The crystal structure is isostructural with other even triclinic, P1BAR n-alkanes.
