Two new benzene tricarboxylato derivatives [(Cy2NH2)](3)[C6H3(CO2)(3)]center dot 4H(2)O (1) and [i-Bu2NH2][(Me3SnO2C)(2)C6H3CO2] (2) have been synthesized and characterized by X-ray crystallography. In the solid state, compound 1 shows a three-dimensional structure involving intra-and intermolecular hydrogen bonds, whereas the X-ray structure of 2 consists of pentacoordinated Sn centers bonded to three methyl groups and two O atoms in a trans-O-2 SnC3 environment, bridged by oxyanions leading to a layered structure; the cation is involved in intramolecular hydrogen bonds.
