Crystals suitable for X-ray analysis were obtained from a mixed solution of dichloromethane and ethanol in a five-to-one volume ratio. The crystal is monoclinic, space group P21/c with crystallographic parameters: a = 15.0129(14) , b = 12.5677(12) , c = 9.7715(9) , β = 98.556(2)°, μ = 0.078 mm−1, V = 1823.1(3) 3, Z = 4, Dc = 1.164 g/cm3, F(000) = 696, T = 296(2) K.

二氢丁苯那嗪 (DTBZ) 是通过在乙醇中用硼氢化钠还原丁苯那嗪来合成的。适用于 X 射线分析的晶体是从体积比为 5 比 1 的二氯甲烷和乙醇的混合溶液中获得的。晶体为单斜晶系,空间群 P21/c,晶体学参数: a = 15.0129(14) , b = 12.5677(12) , c = 9.7715(9) , β = 98.556(2)°, μ = 0.078 mm−1, V = 1823.1(3) 3, Z = 4, Dc = 1.164 g/cm3, F(000) = 696, T = 296(2) K. X 射线分析和手性 HPLC 表明我们制备的 DTBZ方法由 (2R,3R,11bR) 和 (2S,3S,11bS) 对映异构体组成。
