چکیده
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.

In the title coordination polymer, [Cd(C(8)H(5)N(2)O(2)S)(2)(C(10)H(8)N(2))](n), the Cd(II) ion is coordinated by a bidentate 2,2-bipyridyl ligand, two O,O'-chelating 2-amino-1,3-benzothia-zole-6-carboxyl-ate (ABTC) ligands and one N-bonded ABTC ligand. The resulting CdN(3)O(4) coordination polyhedron approximates to a very distorted penta-gonal bipramid with one O and one N atom in axial posit...

In the title compound, [Cd(NO(3))(2)(C(12)H(12)N(6))(2)](n), the Cd(II) cation is located on an inversion center and is six-coordinated by four N atoms from four 1,3-bis-[(1H-1,2,4-triazol-1-yl)meth-yl]benzene (L) ligands and two O atoms from two nitrate anions in a slightly distorted octa-hedral geometry. The ligands link different Cd(II) ions into a ribbon-like structure along [001]. Two O at...

The title compound [Cu(2)(C(6)H(3)BrNO(2))(4)](n), forms sheets in the bc plane. The structure features the dinuclear paddle-wheel cage motif common to copper(II) carboxyl-ates. The polymeric structure is achieved through bridging between binuclear units by the pyridyl donors of two of the four carboxyl-ates of the cage. Each cage engages in axial bonding at each copper atom to a pyridyl nitro-...
