| Abstract: | Crystal structure of the title mesocyclic diamine has been determinedby X-ray diffraction analysis. The crystal belongs to triclinic system, space group P1,with crystallographic parameters C6H14N2O2. 2HBr. EtOH, Mr= 354. 08, a= 7. 813(4), b=8. 109(5), c=11. 153(5) ,a=82. 50(7),β=81. 60(4),γ=75. 53(8)°, V= 673. 5 (7) , Z= 2, Dc= 1. 519g. cm-3,μ= 59. 364 cm-1 (MoKa), F(000) =356, R=0. 082,R.= 0. 095 for 2550 observed reflections with I≥3σ(I). The determination suggests that the molecular ring is folded to make the conformation look like acrown. |
