| pubmed-article:21583142 | pubmed:abstractText | The title compound, C(20)H(22)O(2), crystallizes with two independent mol-ecules in the asymmetric unit. In each mol-ecule, all the non-H atoms lie in a common plane (r.m.s. deviations of 0.098 and 0.079?Å). There is a ?-? stacking inter-action in the crystal structure. The central aromatic rings of the two mol-ecules, which are stacked head-to-tail one above the other, are separated by centroid-to-centroid distances of 3.872?(13) and 3.999?(10)?Å. | lld:pubmed |
