Bis(?-3,5-dinitro-2-oxidobenzoato)-?O,O:O;?O:O,O-bis[aqua-(2-phenyl-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-?N,N)cobalt(II)].

ABSTRACT: In the title compound, [Co(2)(C(7)H(2)N(2)O(7))(2)(C(19)H(12)N(4))(2)(H(2)O)(2)], the Co(II) atom is six-coordinated by two N atoms from a 2-phenyl-1H-1,3,7,8,-tetraaza-cyclo-penta-[l]phenanthrene (L) ligand, three O atoms from two 3,5-dinitro-2-oxidobenzoate (3,5-dinitro-salicylate or DNSA) ligands and one O atom from a water mol-ecule in a distorted octa-hedral geometry. The Co(II) atoms are bridged by two carboxyl-ate O atoms from two DNSA ligands, forming a centrosymmetric dinuclear structure. Neighbouring dinuclear units inter-act with each other through two types of ?-? inter-actions between the L ligands [shortest centroid-centroid distance = 3.646?(3)?Å] and between the L and DNSA ligands [shortest atom-to-centroid distance = 3.794?(3)?Å]. N-H?O, O-H?N and O-H?O hydrogen bonds are observed, which lead to a three-dimensional structure.

Project description:In polymeric title compound, {[Co(2)(C(7)H(2)N(2)O(7))(2)(H(2)O)(6)]·2H(2)O}(n), obtained from the reaction of 3,5-dinitro-salicylic acid with cobalt(II) acetate, both Co(II) atoms are located on inversion centres and exhibit a distorted octahedral coordination geometry. The coordin-ation sphere about one Co(II) atom comprises four O-atom donors from two bidentate chelate (O(phenolate) and O(carbox-yl)) and bridging dianionic ligands and two water mol-ecules [Co-O range = 2.0249 (11)-2.1386 (14) Å], while that about the second Co(II) atom has four water mol-ecules and two bridging carboxyl-ate O-donor atoms [Co-O range = 2.0690 (14)-2.1364 (11) Å]. The coordinated water mol-ecules as well as the water mol-ecules of solvation give O-H⋯O water-water and water-carboxyl hydrogen-bonding inter-actions in the three-dimensional framework structure.

Project description:In the title compound, [Co(C(7)H(2)N(2)O(7))(C(10)H(8)N(2))(2)], the Co(II) atom is coordinated by four N atoms from two 2,2'-bipyridine ligands and two O atoms from a 3,5-dinitro-2-oxidobenzoate ligand, displaying a distorted octa-hedral coordination geometry.

Aqua-(2-hydr-oxy-5-sulfonatobenzoato-?O)bis-(2-phenyl-1H-1,3,7,8-tetra-aza-cyclo-penta-[l]phenanthrene-?N,N)zinc(II).

Project description:In the title compound, [Zn(C(7)H(4)O(6)S)(C(19)H(12)N(4))(2)(H(2)O)], the Zn(II) ion is coordinated by two N,N'-bidentate 2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene ligands, one O-monodentate 5-sulfosalicylate dianion and a water mol-ecule. This results in a distorted cis-ZnO(2)N(4) octa-hedral coordination geometry for the metal ion. In the crystal, mol-ecules are expanded into a three-dimensional supra-molecular motif via O-H?O, O-H?N and N-H?(O,S) hydrogen bonds. In addition, ?-? stacking inter-actions between the aromatic rings of the polycyclic ligands consolidate the sturcture [shortest centroid-centroid distance = 3.501?(2)?Å].

Tetra-aqua-bis-(3,5-dinitro-benzoato-κO (1))magnesium tetra-hydrate.

Project description:In the structure of the title compound, [Mg(C7H3N2O6)2(H2O)4]·4H2O, the slightly distorted octa-hedral MgO6 coord-in-ation polyhedron comprises two trans-related carboxyl-ate O-atom donors from mononodentate 3,5-dinitro-benzoate ligands, and four water mol-ecules. The coordinating water mol-ecules and the four water mol-ecules of solvation give both intra- and inter-unit O-H⋯O hydrogen-bonding inter-actions with carboxyl-ate, water and nitro O-atom acceptors, forming a three-dimensional structure.

Poly[di-μ(5)-adipato-κO:O':O'':O''',O'''-μ(4)-adipato-κO:O':O'':O'''-bis-[2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-κN,N]tricobalt(II)].

Project description:In the title polymer, [Co(3)(C(6)H(8)O(4))(3)(C(19)H(12)N(4))(2)](n), two adipate dianions (C(6)H(8)O(4) (2-)) occupy general positions and two are situated on different inversion centres. The two on general positions bind through their four O atoms to five 2-phenyl-1H-1,3,7,8-tetra-azacyclo-penta-[l]phenanthrene-chelated Co(II) ions, whereas the two on special positions bind to only four. Of the three Co atoms, two are chelated by N-heterocycles; the third is bonded to six O atoms. The bonding mode of the dianion gives rise to a three-dimensional network structure; the network is further consolidated by N-H⋯O hydrogen bonds.

Bis[tetra-aqua-(1,10-phenanthroline-?N,N')cobalt(II)] hexa-aqua-cobalt(II) bis-[3,5-bis-(carboxyl-atometh-oxy)benzoate] tetra-hydrate.

Project description:The title compound, [Co(C(12)H(8)N(2))(H(2)O)(4)](2)[Co(H(2)O)(6)](C(11)H(7)O(8))(2)·4H(2)O, was obtanied by the reaction of cobalt acetate with 3,5-bis-(carb-oxy-meth-oxy)benzoic acid and 1,10-phenanthroline. The asymmetric unit contains one tetra-aqua-(1,10-phenanthroline)cobalt(II) cation, one half of a hexa-aqua-cobalt(II) cation that is completed by inversion symmetry, one 3,5-bis-(carboxyl-atometh-oxy)benzoate trianion and two lattice water mol-ecules. The two Co(II) atoms each show a slightly distorted octa-hedral coordination (CoO(6) and CoO(4)N(2)). The cations, anions and lattice water mol-ecules are linked by an intricate network of O-H?O hydrogen bonds into a three-dimensional structure.

Poly[(μ-3,5-dinitro-2-oxidobenzoato)(μ-3-hydroxy-pyridine)copper(II)].

Project description:A new coordination polymer, [Cu(C(7)H(2)N(2)O(7))(C(5)H(5)NO)](n), exhibits a double-chain structure, in which 3,5-dinitro-2-oxidobenzoate and 3-hydroxy-pyridine both act as bridging ligands, -connecting adjacent copper(II) centers to form an infinite double-stranded chain. The asymmetric unit contains one Cu(II) ion, one 3,5-dinitro-2-oxidobenzoate ligand and a 3-hydroxy-pyridine ligand. Coordination by one N atom and three O atoms from two different 3,5-dinitro-2-oxidobenzoate ligands and a 3-hydroxy-pyridine ligand creates a square-planar Cu(II) center, which is augmented by a less tightly bonded fifth phenol O atom to form a square-pyramidal five-coordinate complex with an essentially planar base. The double-stranded chains are stabilized by intra-chain π-π inter-actions [the centroid-to-centroid distance between adjacent aromatic rings is 3.719 (7) Å], and further linked through O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.

Project description:In the binuclear title complex, [Dy(2)(C(7)H(3)N(2)O(6))(6)(C(12)H(8)N(2))(2)], the Dy(III) ions exhibit a distorted monocapped square-anti-prismatic geometry and are coordinated by seven O atoms of four 3,5-dinitrobenzoate (DNBA) anions and two N atoms of a phenanthroline ligand. The carboxylate groups of the DNBA anions exhibit three coordination modes: bidentate chelating, bidentate chelating-bridging and tridentate chelating-bridging. The center of the mol-ecule is located on a crystallographic center of inversion.
