The solid state structures of the (-)-n-heptylcarbamate of geneseroline and its hydrochloride salt were determined by single crystal X-ray diffraction analysis. Both compounds gave crystals belonging to the orthorombic P2(1)2(1)2(1) space group with a = 27.597(7) A, b = 8.899(2) A, c = 9.290(2) A, V = 2281.5(9) A3, Z = 4, and R = 0.0682 for the base and a = 11.300(1) A, b = 8.3485(5) A, c = 24.141(2)
通过单晶X射线衍射分析确定了吉色啉的(-)-正庚基氨基甲酸酯及其盐酸盐的固态结构。两种化合物均给出了属于正交排列的P2(1)2(1)2(1)空间群的晶体,其中a = 27.597(7)A,b = 8.899(2)A,c = 9.290(2)A,V = 2281.5 (9)A3,Z = 4,对于基数R = 0.0682,a = 11.300(1)A,b = 8.3485(5)A,c = 24.141(2)A,V = 2277.3(3)A3,Z = 4,盐的R = 0.0482。X射线和1H NMR分析表明该碱是1,2-恶嗪衍生物。六元环在固态时采用4C1椅子构象,而在CDCl3溶液中,它以两种可能的椅子构象子4C1和1C4的混合物形式存在,N-甲基位于赤道位置(比率约为75:25)。该盐是一种N-氧化物衍生物。该五元环在固态和CDCl3溶液中采用不同的包膜构象,表明具有一定的灵活性。在极性更
