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

ABSTRACT: 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.

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].

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

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.

Project description:In the crystal of the title compound, C(15)H(18)N(2)O(4)S, inversion dimers are formed by inter-molecular N-H?N hydrogen bonds and weak C-H?O contacts. These dimers stack up along [100] through inversion-related ?-? inter-actions between thia-zole rings [centroid-centroid distance = 3.790?(2)?Å] and the thia-zole and benzene rings [centroid-centroid distance = 3.845?(2)?Å] and C-H?? contacts.

catena-Poly[[diaqua-strontium]-bis-(?-quinoline-3-carboxyl-ato)].

Project description:The title compound, [Sr(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), contains an eight-coordinate Sr(II) ion displaying a distorted square-anti-prismatic geometry, two quinoline-3-carboxyl-ate ligands and two terminal water mol-ecules. The Sr(II) atom is surrounded by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands and two O atoms from two coordinated water mol-ecules. The bridging carboxyl-ate O atoms [Sr-O = 2.498?(3) and 2.495?(3)?Å] link Sr(II) atoms, forming a chain substructure extending along the c axis. The chains are linked by O-H?N and O-H?O hydrogen bonds, giving a three-dimensional framework structure.

catena-Poly[[diaqua-calcium(II)]-bis-(?-quinoline-3-carboxyl-ato)].

Project description:In the title complex, [Ca(C(10)H(6)NO(2))(2)(H(2)O)(2)](n), the Ca(II) ion is eight-coordinated by six carboxyl-ate O atoms from four separate quinoline-3-carboxyl-ate ligands, two of which are bidentate chelate and two bridging, and two water mol-ecules in a distorted square-anti-prismatic geometry. The bridging groups form a polymeric chain substructure extending along the c axis, the chains being connected by coordinated-water O-H?N and O-H?O(carboxyl-ate) hydrogen bonds into a three-dimensional framework structure.

Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.

2,2'-(Sulfanediyldimethyl-ene)bis-(1,3-benzothia-zole).

Project description:In the title compound, C(16)H(12)N(2)S(3), the two benzothia-zole groups are oriented differently with respect to the -CH(2)- groups, one being approximately staggered and one nearly eclipsed. A sulfur-? inter-action of 3.3627?(11)?Å is observed between the bridging thio-ether S atom and a thia-zole ring. The crystal packing is further stabilized by inter-molecular C-H?N and C-H?? inter-actions.

catena-Poly[bis-(4-amino-pyridinium) [[tetra-aqua-nickel(II)]-?-benzene-1,2,4,5-tetra-carboxyl-ato] dihydrate].

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

Bis(1,3-benzothia-zole-2-thiol-ato)[(Z)-methyl 2-(2-amino-1,3-thia-zol-4-yl)-2-(methoxy-imino)acetate]nickel(II).

Project description:In the title compound, [Ni(C(7)H(4)NS(2))(2)(C(7)H(9)N(3)O(3)S)], the Ni(II) ion is in a slightly distorted N(4)S(2) octa-hedral coordination environment. The two benzothia-zole-2-thiol-ate ligands chelate via their thia-zole N and thiol-ate S atoms while the methyl 2-(2-amino-thia-zol-4-yl)-2-(methoxy-imino)acetate also acts as a chelate ligand binding through the thia-zole and imino N atoms. Intra-molecular N-H?N, C-H?N and C-H?O inter-actions contribute to the mol-ecular conformation. In the crystal structure, inter-molecular N-H?O hydrogen bonds produce R(1) (2)(6) rings and generate chains along the c axis. An extensive one-dimensional supra-molecular network of N-H?O hydrogen bonds and C-H?? inter-actions is responsible for the crystal structure stabilization.

catena-Poly[lead(II)-bis-(?(2)-pyridazine-3-carboxyl-ato-?N,O:O)].

Project description:In the title structure, [Pb(C(5)H(3)N(2)O(2))(2)](n), the Pb(II) ion is six-coordinated by two pyridazine-3-carboxyl-ate ligands via N and O atoms, with the carboxyl-ato O atoms acting as bidentate and bridging adjacent Pb(II) ions, giving rise to catenated mol-ecular ribbons propagating along the a-axis direction. The ribbons are connected by C-H?O hydrogen bonds and van der Waals inter-actions.
