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

ABSTRACT: 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.

Project description: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[(?-benzene-1,2,4,5-tetra-carboxyl-ato)tetra-silver(I)].

Project description:In the centrosymmetric title compound, [Ag(4)(C(10)H(2)O(8))](n), the benzene ring has irregular bond lengths but remains planar (r.m.s. deviation 0.0002?Å). The Ag-O bond lengths are in the range 2.153?(3)-2.615?(4)?Å. The carboxyl-ate groups are oriented at dihedral angles of 26.4?(5) and 74.9?(4)° to the benzene ring. The coordination behaviour of each carboxyl-ate O atom is different: in one carboxylate, the O atoms are coordinated to a single and two Ag atoms; in the other carboxylate, the O atoms are coordinated to two and three Ag atoms. Non-classical inter-molecular C-H?O hydrogen bonding is present in the crystal structure. The title compound forms a three-dimensional polymeric network due to the coordination of the Ag atoms.

Project description:In the polymeric complex of the title compound, {[AgNi(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)]NO(3)·2H(2)O}(n), the Ag(I) ion displays an angular coordination geometry with two N atoms from pyrazine-2-carboxyl-ate ligands, and the Ni(II) ion is hexa-coordinated by two O atoms from two water mol-ecules, two O and two N atoms from pyrazine-2-carboxyl-ate ligands in a distorted octa-hedral geometry. In the crystal, the Ag(I) and Ni(II) ions lie on a mirror plane and an inversion centre, respectively. The complex chains, the nitrate ions and the uncoordinated water mol-ecules are linked together through O-H?O hydrogen bonds and weak Ag?O inter-actions [2.619?(17)-2.749?(17)?Å] into a three-dimensional network.

catena-Poly[lead(II)-bis-(?-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 ?-? inter-actions [centroid-centroid distance = 3.7436?Å] between ABTC rings and N-H?O and N-H?N hydrogen bonds.

catena-Poly[silver(I)-?-acridine-9-carboxyl-ato-?N:O,O'].

Project description:In the title coordination polymer, [Ag(C(14)H(8)NO(2))](n), the Ag(I) cation is coordinated by two O atoms and one N atom from two symmetry-related acridine-9-carboxyl-ate ligands in a distorted trigonal-planar geometry. The metal atoms are connected by the ligands to form chains running parallel to the b axis. ?-? stacking inter-actions [centroid-to-centroid distances 3.757?(2)-3.820?(2)?Å] and weak Ag?O inter-actions further link the chains to form a layer network parallel to the ab plane. The Ag(I) cation is disordered over two positions, with refined site-occupancy factors of 0.73?(3):0.27?(3).

Poly[(?(3)-quinoline-6-carboxyl-ato-?(3)N:O:O')silver(I)].

Project description:In the title coordination polymer, [Ag(C(10)H(6)NO(2))](n), the Ag(I) cation is coordinated by two O atoms and one N atom from three 6-quinoline-carboxyl-ate anions in a distorted T-shaped AgNO(2) geometry, in which the O-Ag-O angle is 160.44?(9)°. The 6-quinoline-carboxyl-ate anion bridges three Ag(+) cations, forming a nearly planar polymeric sheet parallel to (101). The distance between Ag(+) cations bridged by the carboxyl group is 2.9200?(5)?Å. In the crystal, ?-? stacking is observed between parallel quinoline ring systems, the centroid-centroid distance being 3.7735?(16)?Å.

Project description: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 positions. One of the ABTC ligands is bridging to an adjacent metal atom, generating an infinite chain propagating in [100]. A three-dimensional network is constructed from N-H?O and N-H?N hydrogen bonds and aromatic ?-? stacking inter-actions [centroid-centroid separations = 3.641?(2) and 3.682?(3)?Å].

Poly[bis-(?-hemihydrogen 2-phenyl-quinoline-4-carboxyl-ato-?N,O)silver(I)].

Project description:In the title compound, [Ag(C(16)H(10.5)NO(2))(2)], the Ag(I) cation (site symmetry 2) is coordinated by two N atoms in a near-linear AgN(2) arrangement. Two carboxyl-ate O atoms from two additional 2-phenyl-quinoline-4-carboxyl-ate ligands form long Ag-O bonds [2.6585?(17)?Å], resulting in a distorted square-planar arrangement. The bridging ligands result in infinite corrugated sheets propagating in (010). An O-H?O hydrogen bond, disordered about a twofold axis, completes the structure.

Project description:In the title coordination polymer, [Na(C(4)H(2)N(3)O(4))(H(2)O)(2)](n), the Na(I) atom is six-coordinated by one O atom and one N atom from a 2H-1,2,3-triazole-4-carb-oxy-5-carboxyl-ate ligand and four O atoms from four water mol-ecules, forming a distorted octa-hedal geometry. The Na(I) atoms are bridged by water mol-ecules into a chain structure along [100]. Inter-molecular N-H?O, O-H?N and O-H?O hydrogen bonds connect the chains. An intra-molecular O-H?O hydrogen bond between the carboxyl-ate groups is observed.
