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).

Project description:In the title compound, C(17)H(17)ClN(2)O(2), the asymmetric unit contains half a mol-ecule with a centre of symmetry at the mid-point of the central C-C bond. The conformations of the amide O atoms are anti to the methyl-ene atoms. Further, the N-H bonds in the amide fragments are anti to the ortho-chloro/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 62.0?(2)°. In the crystal, a series of N-H?O inter-molecular hydrogen bonds link the mol-ecules into column-like infinite chains along the a axis. The methyl and Cl groups are disordered with respect to the ortho positions of the benzene ring, with site-occupation factors of 0.5 each.

Bis[1-(2,3-di-methyl-phen-yl)piperazine-1,4-diium] bis-(oxonium) cyclo-hexa-phosphate dihydrate.

Project description:In the title compound, 2C12H20N2 (2+)·2H3O(+)·P6O18 (6-)·2H2O, a protonated water mol-ecule bridges the centrosymmetrical anionic P6O18 ring via O-H?O hydrogen bonds. The centrosymmetric hydrogen-bonded rings formed by four oxonium cations and four phosphate anions can be described by an R 4 (8)(36) graph-set motif. The ring motifs are connected by hydrogen bonds into inorganic layers perpendicular to [100]. The 1-(2,3-di-methyl-phen-yl)piperazine-1,4-diium cations are located between the layers, compensating their negative charge and establishing N-H?O hydrogen bonds with the O atoms of the anionic framework.
