Crystal Structure of (S)-(+)-5-Nitronaproxen

抄録

(S)-(+)-5-nitronaproxen (5-nitro-(S)-(+)-6-methoxy-α-methyl-2-naphthalenacetic acid) I was synthesized to study its SHG property. The compound crystallizes in the monoclinic system and has been characterize as follows: P2₁, a = 7.8950(6)Å, b = 7.4518(5)Å, c = 22.4176(16)Å, β = 99.494(2)°, Z = 4, V = 1300.81(16)ų, D_c = 1.405 Mg/m³. A powder SHG measurement indicates that the SHG response of the title compound I is about 1.5-times that of urea.
