Abstract: | The compound N-methyl-piperidinium-acet-para-anilide-iodide crystallizes in the triclinic space group P1 with 2 molecules in the unit cell of dimensions a = 7.164, b = 16.818, c = 6.974 Å, α = 94.20, β = 102.95, γ = 86.15°. The accurate measurement of the intensities of the X-ray reflexions by an automatic four circle diffractometer allowed the determination of the positions of the hydrogen atoms in this heavy atom structure containing one iodine atom per molecule. The final R value is 0.097 for all 3033 reflexions. |
