RESUMO
The structure of the title compound, [Cu(C14H9NO4)(C12H8N2)] n , consists of zigzag polymeric chains along the c axis. The asymmetric unit contains one Cu(II) atom which is coordinated by one 2,2'-imino-dibenzoate ligand and a one phenanthroline unit. Two intra-molecular N-Hâ¯O hydrogen bonds occur. The supra-molecular structure is characterized by weak C-Hâ¯O hydrogen bonds and π-π stacking inter-actions, forming a three-dimensional supramolecular network. The shortest centroid-centroid distances between neighbouring phenanthroline aromatic rings and 2,2'-imino-dibenzoate rings are 3.684â (1) and 3.640â Å, respectively. The shortest intra-chain Cuâ¯Cu distance is 7.2885â (9) and the shortest Cuâ¯Cu distance between Cu atoms in different chains is 7.1103â (6)â Å.
RESUMO
In the title Schiff base, C21H14N4O4, the dihedral angle between the two nitro groups and the central benzene ring are 83.6â (5) and 2.6â (6)°. The anthracene ring system and the benzene ring make a dihedral angle of 0.7â (2)°. Intra-molecular N-Hâ¯O and C-Hâ¯N hydrogen bonds occur. In the crystal, C-Hâ¯O hydrogen bonds link the mol-ecules, forming chains along the b-axis direction.
