C22H28, M(r) = 292.4, monoclinic, C2/c, a = 25.691 (4), b = 5.663 (1), c = 13.279 (2) angstrom, beta = 113.83 (1)-degrees, V = 1767.3 (4) angstrom 3, Z = 4, D(x) = 1.06 Mg m-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 0.63 mm-1, F(000) = 640, T = 293 K, R = 0.048 for 1137 observed reflections. The 2,6-dicyclohexylnaphthalene contains a crystallographic symmetry centre. The presence of two bulky substituents involves only slight deviation from flatness for the naphthalene ring. The cyclohexyl substituents adopt a chair conformation.
