I am not a chemist, but when I compare this image with the one in the patent, the relative orientations of individual bonds look quite different. Does this matter? --IO Device (talk) 18:57, 30 September 2014 (UTC)[reply]
Those particular bonds are freely rotatable, so their relative orientations don't matter in a standard 2D depiction. ChemNerd (talk) 20:35, 2 October 2014 (UTC)[reply]
