N,N'-Bis(3-methyl-phen-yl)succinamide dihydrate.

ABSTRACT: The asymmetric unit of the title compound, C(18)H(20)N(2)O(2)·2H(2)O, contains half a mol-ecule 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)-CH(2) segment in the two halves of the mol-ecule is 5.6 (4)°. In the crystal, the packing of mol-ecules through O-H⋯O and N-H⋯O hydrogen-bonding inter-actions 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).
