摘要: X-ray diffraction (~MoK~, 0/20 scan) has been used to determine the crystal structures of 2'-nitrobenzenesulfoanilide (I, R = 0.0425 from 2286 reflections) and its PhHg derivative (II, 0.0329 2069 reflections). The molecule compound Icontains an intramolecular hydrogen bond N-~...O medium strength involving 0 atom nitro-group (N...O 2.593(2) ~, angle N--H...O 139(2)~ which closes a planar six-membered ring. In II, as resul$ weak coordination Hg...O| (NO=) at distance 3.00(1) A, chelate ring is formed. Analysis details molecular geometry published data indicates that formed by H-bond in I greater than II.
