4,4′-Dinitro-2,2′-[propane-1,3-diylbis(iminiumylmethanylylidene)]diphenolate
نویسنده
چکیده
The title compound, C(17)H(16)N(4)O(6), is a Schiff base, which is found as a bis-zwitterion in the solid state. The geometry around the iminium N atom indicates sp(2)-hybridization. The diiminiumpropyl-ene chain is in an approximate double-gauche conformation, with average N-C-C-C torsion angles of 69.3°. The zwitterion shows strong intra-molecular N-H⋯O hydrogen bonds between the iminium N and phenolate O atom. In the crystal, bifurcated N-H⋯(O,O) hydrogen bonds assemble pairs of molecules into inversion dimers.

In the title compound, [CuZnCl(2)(C(19)H(20)N(2)O(4))], the Cu(II) ion exhibits a slightly distorted square-planar coordination geometry defined by two N atoms and two O atoms of the 6,6'-dimeth-oxy-2,2'-[propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenolate Schiff base ligand. The Zn(II) ion is also four-coordinated by the two phenolate O atoms of the Schiff base ligand and by two cis-coordina...

The title compound, C(17)H(14)Cl(4)N(2)O(2), is generated by crystallographic twofold symmetry. The two benzene rings are inclined to one another by 80.17 (10)°. There are two intra-molecular O-H⋯N hydrogen bonds, which make S(6) ring motifs. In the crystal, mol-ecules are linked by C-H⋯O and weak C-H⋯Cl inter-actions, forming a three-dimensional network.
