Abstract
The 2,9-dimethyl-1,2,3,4,7,8,9,10-octahydro-1,10-phenanthroline( 1) was successfully synthesized by the reaction of 2,9-dimethyl-1,10-phenanthroline and sodium cyanoborohydride,and characterized by elemental analysis,nuclear magnetic resonance and high resolution mass spectrum. The single crystals of compound 1 were growth by volatilization method and characterized by X ray single crystal diffraction. In compound 1,the 2,9-dimethyl-1,2,3,4,7,8,9,10-octahydro-1,10-phenanthroline molecule adopted a twisted chair conformation. The adjacent molecules pack with cross-stacking mode,and connect each other with weak C-H…π interaction,forming 1D supramolecule chain. Crystal data were triclinic,space group P-1,a = 9. 052( 9),b = 10. 241( 9) ,c = 14. 809( 12),α = 71. 07( 5),β = 79. 79( 3) ,γ = 77. 22( 4) ,Z = 1,and V = 1258( 2)3.
