  ABSTRACT: All non-H atoms of the title compound, C(7)H(7)NO(2)S, lie on a crystallographic mirror plane, with the two methyl-ene H atoms bis-ected by this plane. The crystal packing is characterized by inter-molecular C-H⋯O and O-H⋯N contacts, which link the mol-ecules into infinite zigzag chains parallel to [010].

  ABSTRACT: In the title molecular salt, C(21)H(25)N(4)S(3) (+)·ClO(4) (-), an intra-molecular N-H⋯N hydrogen bond stabilizes the conformation of the cation. The three N-C-C-S torsion angles are 91.7 (2), 100.9 (2) and 167.02 (14)°.

  ABSTRACT: The title complex, [Cu(C(8)H(5)O(4))(NO(3))(C(18)H(10)N(4))(H(2)O)], was synthesized by reacting Cu(NO(3))(2), isophthalic acid and dipyridophenazine under hydro-thermal conditions. The Cu(II) ion is in a slightly distorted square-pyramidal coordination environment. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect complex mol-ecules into chains along [001].

  ABSTRACT: The title copper coordination polymer, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(10)H(8)N(2))(2)](n), was synthesized by reacting Cu(NO(3))(2), isophthalic acid and 1,10-phenanthroline under hydro-thermal conditions. The trinuclear unit presents a central almost planar CuO(4) chromophore with the cation on a symmetry center, and two symmetry-related CuN(2)O(3) groups with the metal centre in a distorted square-pyramidal environment. These units are bridged by isophthalate ligands into one-dimensional double-chain coordination polymers which are, in turn, connected by various π-π stacking inter-actions (face-to-face distance ca 3.45 Å) and O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.
