Synthesis and Crystal Structure of 10-(4-nitrophenymethylidyne)-9,10- dihydrofluorene

摘要：

A novel compound of 10-(4-nitrophenymethylidyne)9,10-dihydrofluorene(C20H13NO2,Mr=299.31)was synthesized via Knoevenagel reaction in the resence of sodium hydroxide under solvent-free condition. The advantages of this procedure were mild reaction conditions, simple protocol, and high yield(93％). Its structure was determined IR, 1H NMR, MS, elemental analysis and X-ray diffraction. The crystal of the new compound is Orthorhombic, space group Pbca with a = 11.6269(10), b = 7.6792(6), c = 33.862(3) A, = 9Q, = 90, = 90o, V= 3023.4(4) A3, Z=8, Dc=1.315g/cm3,u= 0.085 mm-1, F(000)=1248, R=0.0589 and wR = 0.1284 for 2751 observed reflection with I>2 o (I), ji-jt stacking interactions contribute to the stability of the structure.
