In the title mononuclear complex, [Cd(C(8)H(7)O(2))(2)(H(2)O)(2)], the Cd(II) atom possesses crystallographically imposed C(2) site symmetry, and is coordinated by four O atoms from two 4-methyl-benzoate ligands and two water mol-ecules, displaying a distorted octa-hedral geometry. The molecules are assembled via inter-molecular O-H⋯O hydrogen-bond inter-actions into a supra-molecular architect...

In the title compound, C(3)H(5)N(2) (+)·C(7)H(4)NO(4) (-), the benzene ring forms a dihedral angle of 40.60 (5)° with the imidizolium ring. The nitro-benzoate anion is approximately planar: the benzene ring makes dihedral angles of 3.8 (3) and 3.2 (1)° with the nitro and carboxyl-ate groups, respectively. In the crystal structure, the cations and anions are linked by inter-molecular N-H⋯O hydro...

In the title coordination polymer, [Ag(C(7)H(6)NO(2))(C(6)H(12)N(4))(H(2)O)](n), the Ag(I) ion is five-coordinated by two carboxyl-ate O atoms from one 4-amino-benzoate anion (L), two N atoms from two different hexa-methyl-enetetramine (hmt) ligands, and one water O atom in a distorted square-pyramidal geometry. The metal atom lies on a mirror plane and the L anion, hmt ligand and water mol-ecu...

The title compound, C(28)H(20)N(2)O(4), was synthesized by the reaction of 2-(hydrazonometh-yl)phenyl benzoate with iodine. The mol-ecule possesses a crystallographically imposed center of symmetry at the mid-point of the hydrazine N-N bond. The substituents at the ends of the C=N bonds adopt an E,E configuration. Inter-molecular C-H⋯π(arene) hydrogen bonds and aromatic π-π stacking inter-actio...

In the title compound, [Cu(2)(C(7)H(3)ClNO(4))(4)](n), the coordination geometry around each Cu(II) ion is distorted square-pyramidal. The CuO(5) coordination is formed by five O atoms from the carboxyl-ate groups of five 5-chloro-2-nitro-benzoate ligands. This coordination leads to the formation of centrosymmetric binuclear units which are edge-shared, forming a linear chain along the a axis, ...
