摘要：

The three-dimensional crystal structure of a commercial paraffin wax has been determined from electron diffraction intensity data collected From epitaxially oriented samples. The orthorhombic space group is A2(1)am, where a = 7.46(5) Angstrom, b = 4.97(1) Angstrom, c/2 = 41.2(1) Angstrom. On average, the lamellar packing resembles the B-form of n-C31H64. Although disorder occurs near the lamellar surfaces, as indicated by fractional atomic occupancies, the final structure (R = 0.19, based on 38 unique hkl intensities) is still very well-ordered.
