Brucine and two solvates.
The crystal structures of brucine (2,3-dimethoxystrychnidin-10-one), C(23)H(26)N(2)O(4), brucine acetone solvate, C(23)H(26)N(2)O(4).C(3)H(6)O, and brucine 2-propanol solvate dihydrate, C(23)H(26)N(2)O(4).C(3)H(7)O.2H(2)O, have been determined. Crystals of brucine and its 2-propanol solvate dihydrate exhibit similar monolayer sheet packing, whereas crystals of the acetone solvate adopt a different mode of packing, as brucine pillars. The solvent appears to control the brucine self-assembly on the basis of common donor-acceptor properties of the surfaces.
