摘要

The title compound of 2-nitro-9,9-bis(methylpropionate)fluorine (C21H21NO6, Mr = 383.39) was synthesized for the first time. Complete assignments were achieved by 1H NMR, IR, EI-MS, elemental analysis and single-crystal X-ray diffraction technique. The crystal belongs to monoclinic, space group P21/c with a = 11.4581(15), b = 10.3624(14), c = 16.573(2) A.,/? = 96.629(2)°, V = 1954.6(5) A3, Z = 4, Dc = 1.303 g/cm3, p = 0.096 mm-1, F(000) = 808, R = 0.0493 and wR = 0.1499 for 3107 observed reflections with I 〉 2tr(/). X-ray analysis reveals that three fused rings of the fluorene system are almost coplanar and the two ester groups are nearly perpendicular to the fused-ring system. Weak C-H...O hydrogen bonding connects the molecules into centrosymmetric dimmers.
