Crystal structure of rac-(3a'R,9a'R)-3a'-(indol-3-yl)-1#8242;,2#8242;,3#8242;,3a',4#8242;,9a'-hexa#173;hydro#173;spiro#173;cyclo#173;pentane-1,9#8242;-penta#173;leno1,2-bindole p-xylene hemisolvate

摘要

The title compound, C26H26N2#183;0.5C8H10, is the first reported characterized 2:2 product from acid-catalyzed condensation of indole with cyclo#173;penta#173;none and no other 2:2 products were observed. Recrystallization from p-xylene gave the title hemisolvate with the p-xylene mol#173;ecule located about an inversion center. The terminal penta#173;lene ring is envelope-flap disordered at the C atom farthest from the skeletal indole unit, with a refined occupancy ratio of 0.819#8197;(4):0.181#8197;(4). The major component has this C atom bent away from the spiro-fused cyclo#173;pentane ring. In the crystal, mol#173;ecules are connected by N#8212;H#8943;#960; inter#173;actions, forming chains along 100, and N#8212;H#8943;#960; and C#8212;H#8943;#960; inter#173;actions, forming chains along 001, which results in the formation of slabs parallel to (010).
