Catena-Poly[[diaqua-(1,2,3-benzothia-diazole-7-carboxyl-ato-?O)copper(II)]-?-1,2,3-benzothia-diazole-7-carboxyl-ato-?N:O].

ABSTRACT: In the polymeric title complex, [Cu(C(7)H(3)N(2)O(2)S)(2)(H(2)O)(2)](n), the Cu(II) centre is surrounded by three 1,2,3-benzothia-diazole-7-carboxyl-ate and two water mol-ecules. A 1,2,3-benzothia-diazole-7-carboxyl-ate ligand bridges two Cu(II) centres, with a Cu?Cu distance of 9.006?(2)?Å. The four O atoms in the equatorial planes around each Cu(II) centre form a distorted square-planar arrangement, while the distorted square-pyramidal coordination is completed by the symmetry-related N atoms of the bridging 1,2,3-benzothia-diazole-7-carboxyl-ate ligands. In the crystal structure, inter-molecular O-H?O and O-H?N hydrogen bonds link the mol-ecules into a three-dimensional supra-molecular network.

Poly[(?(4)-1,2,3-benzothia-diazole-7-carboxyl-ato)silver(I)].

Project description:In the crystal structure of the title compound, [Ag(C(7)H(3)N(2)O(2)S)](n), the Ag(I) atom is coordinated by two N atoms and three O atoms of four organic ligands forming a distorted square pyramid. The carboxyl-ate group acts as a bidentate ligand on one Ag(I) atom and as a bridging group for a symmetry-related Ag(I) atom, forming a dimer. Futhermore, the two N atoms of two thia-diazole rings bridge a third symmetry-related Ag(I) atom, forming a six-membered ring. These two frameworks, AgO(2)Ag and AgN(4)Ag, extend in three directions, forming a three-dimensionnal polymer. The whole polymer is organized around inversion centers.

catena-Poly[lead(II)-bis-(μ-2-amino-1,3-benzothia-zole-6-carboxyl-ato)].

Project description:The title complex, [Pb(C(8)H(5)N(2)O(2)S)(2)](n), consists of one Pb(II) ion located on a crystallographic twofold axis and two symmetry-related 2-amino-1,3-benzothia-zole-6-carboxyl-ate (ABTC) ligands. The central Pb(II) ion has a (4 + 2) coordination by four O atoms of the two ABTC ligands and two weaker Pb-S bonding inter-actions (Pb-S secondary bonds) from S atoms of other two neighbouring ABTC ligands. These bonds link the metal ions into zigzag chains along the c axis, which, in turn, aggregate through π-π inter-actions [centroid-centroid distance = 3.7436 Å] between ABTC rings and N-H⋯O and N-H⋯N hydrogen bonds.

The chains are further connected via O-H?O hydrogen-bonding inter-actions and quinoline ring ?-? inter-actions [centroid-centroid distance = 3.725?(4)?Å], generating a three-dimensional structure. Lattice water mol-ecules participate in the crystal structure via O-H?O hydrogen bonds.
