标题化合物,C16H19FN3O3+C l-,形成的离子化合物由质子化的诺氟沙星阳离子C16H19FN3O3+和阴离子C l-组成.它属于单斜晶系,P 21/c空间群,晶胞参数:Mr=355.79,a=1.234 4(3)nm,b=0.696 53(14)nm,c=1.947 1(4)nm,β=103.40(3),°V=1.628 6(6)nm3,Z=4,Dc=1.443 M g/m3,F(000)=736,μ=0.265 mm-1,R1=0.040 5,wR2=0.102,3 635独立衍射点(I>2σ(I)).晶体堆积通过π-π堆积和与哌嗪的NH,C—H,和羧基O以及C l-有关的分子间氢键作用而稳定,这些作用力使晶体沿着ac平面形成二维的无限网络结构.
The title compound, C16H19FN3O3 + C l-, formed by the protonated norfloxacin cation C16H19FN3O3 + and anion C l- It belongs to the monoclinic system, P 21 / c space group, cell parameters: Mr = 355.79, a = 1.234 4 (3) nm, b = 0.696 53 (14) nm, c = 1.947 1 4 nm, β = 103.40 (3) Dc = 1.443 M g / m 3, F (000) = 736, μ = 0.265 mm -1, R1 = 0.040 5, wR2 = 0.102 and 3 635 independent diffraction points (I> 2σ (I) The π stacking is stabilized by the intermolecular hydrogen bonding associated with the NH, C-H, and carboxyl O and Cl-piperazines, which forces the crystal to form a two-dimensional, infinite network structure along the ac plane.
