Crystal structure of bis(4-methoxyphenyl) malonate
The complete mol-ecule of the title compound, C17H16O6, is generated by crystallographic twofold symmetry, with the central methyl-ene C atom lying on the rotation axis. The carbonyl O atom is disordered over two adjacent positions in a 0.63 (3):0.37 (3) ratio and the dihedral angle between the benzene rings in the two halves of the mol-ecule is 79.31 (12)°. In the crystal, mol-ecules are conne...
متن کامل2,3-Diaminopyridinium hydrogen malonate
In the title mol-ecular salt, C5H8N3(+)·C3H3O4(-), the cation is essentially planar, with a maximum deviation of 0.005 (1) Å for all non-H atoms. In the anion, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, the cations and anions are connected via N-H⋯O hydrogen bonds and a weak C-H⋯O inter-action, forming layers parallel to the ab plane.
متن کامل3,4-Diaminopyridinium hydrogen malonate
In the title salt, C5H8N3 (+)·C3H3O4 (-), the 3,4-di-amino-pyridinium cation is almost planar, with an r.m.s. deviation of 0.02 Å. The conformation of the hydrogen malonate anion is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring. In the crystal, N-H⋯O hydrogen bonds link cations and anions into layers parallel to the ab plane.
متن کاملMelaminium hydrogen malonate
The melaminium (2,4,6-triamino-1,3,5-triazin-1-ium) cation in the title compound, C(3)H(7)N(6) (+)·C(3)H(3)O(4) (-), is essentially planar, with a r.m.s. deviation of the non-H atoms of 0.0085 Å. Extensive hydrogen bonding of the types N-H⋯N and N-H⋯O between cations and cations and between cations and hydrogen malonate (2-carb-oxy-ethano-ate) anions leads to the formation of supra-molecular la...
متن کاملCrystal structure of 3,4-dichloroanilinium hydrogen phthalate
In the title salt, C6H6Cl2N(+)·C8H5O4 (-), the carb-oxy-lic acid and carboxyl-ate groups of the anion form dihedral angles of 20.79 (19) and 74.76 (14)°, respectively, with the plane of the benzene ring. In the crystal, mol-ecules are assembled into a two-dimensional polymeric network parallel to (100) via N-H⋯O and O-H⋯O hydrogen bonds. In addition, within the layer, there are π-π stacking int...
