ABSTRACT: The title compound, {[Ni(C(9)H(4)O(6))(C(14)H(14)N(4))]·0.41H(2)O}(n), exhibits a three-dimensional hydrogen-bonded supramolecular framework. The Ni(II) cation is six-coordinated in a distorted triangular prism defined by two N atoms from two 1,3-bis(imidazol-l-ylmethyl)benzene (bix) ligands and four O atoms from two 5-carboxybenzene-1,3-dicarboxylate (HBTC) dianions. The bix molecules and HBTC dianions both act as bidentate ligands, linking the Ni(II) cations to form a one-dimensional coordination polymer. A two-dimensional wave-like net is constructed by O-H...O hydrogen bonds linking adjacent chains. Partially occupied solvent water molecules fill the cavities and link these layers to form a three-dimensional supramolecular structure via O-H...O hydrogen bonds. The title compound was also characterized by powder X-ray diffraction and thermogravimetric analysis.

ABSTRACT: In the title mol-ecular salt, C(14)H(13)N(2)O(2) (+)·ClO(4) (-), the ring systems in the cation are almost coplanar [dihedral angle = 5.53 (13)°]. Intra-molecular N-H⋯O and O-H⋯O hydrogen bonds generate S(6) and S(5) rings, respectively. In the crystal, the two H atoms involved in the intra-molecular hydrogen bonds also participate in inter-molecular links to acceptor O atoms of the perchlorate anions. A simple inter-molecular N-H⋯O bond also occurs. Together, these form a double-chain structure along [101].
