Crystal data and X-ray powder diffraction data of two derivatives of 4-chloro-2,2'-iminodibenzoic acid: diethyl 4-chloro-2,2'iminodibenzoate, C_18H_18ClNO_4, and dimethyl 4-chloro-2,2'-iminodibenzoate, C_16H_14ClNO_4

摘要

Two derivatives of 4-chloro-2,2'-iminodibenzoic acid: diethyl 4-chloro-2,2'iminodibenzoate, C_18H_18ClNO_4, and dimethyl 4-chloro-2,2'-iminodibenzoate C_16H_14ClNO_4, have been investigated By means of X-ray powder diffraction. The unit cell dimensions were determined from Diffractometer methods, using monochromatic CuKα_1 radiation, and evaluated by indexing Programs. The monoclinic cell found for diethyl 4-chloro-2,2'-iminodibenzoate was a =21.332 (3) A, b=7.889(2) A, c=10.156(2) A, β=91.43 (1)°,Z=4, space group P2 (No. 3), Pm (No. 6), or P2/m (No. 10), D_x=1.351 mg/m~3.
