N,N'-Bis(3-methyl­phen­yl)succinamide dihydrate

B. S. Saraswathi, S. Foro and B. T. Gowda

Abstract: The asymmetric unit of the title compound, C18H20N2O2·2H2O, contains half a mol­ecule with a center of symmetry at the mid-point of the central C-C bond. The N-H bonds in the amide fragments are anti to the meta-methyl groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH2 segment in the two halves of the mol­ecule is 5.6 (4)°. In the crystal, the packing of mol­ecules through O-H...O and N-H...O hydrogen-bonding inter­actions leads to the formation of layers parallel to the bc plane. The methyl group is disordered with respect to the 3- and 5-positions of the benzene ring, with site-occupation factors of 0.910 (8) and 0.090 (8).
