Abstract
Bis(ortho-aminobenzoato)zinc(II), Zn(H2NC6H4COO)2, is monoclinic, space group P21c, with a = 13.938(2) A, b = 5.207(1) A, c = 9.346(1) A, β = 108.37°, Z = 2. The structure was solved by direct and Fourier methods and refined to a final R of 0.047 based on 1198 observable reflections. The zinc is octahedrally coordinated, with four equatorial positions occupied by two amino nitrogen atoms and two carboxylate oxygen atoms such that both the nitrogen and oxygen atoms are in trans positions. The axial positions are occupied by two carbonyl oxygen atoms belonging to two other ligands not associated with the equatorial sites. The extreme insolubility of the compound may be accounted for not only by the two-dimensional polymeric network of carboxylate bridges between zinc atoms in the (100) plane, but also by the presence of hydrogen bonding between ligand molecules.
