Catena-Poly[[bis-(dimethyl sulfoxide-?O)cerium(III)]tris-(?(2)-3,5-dinitro-benzoato-?O:O')].

ABSTRACT: The polymeric title compound, [Ce(C(7)H(3)N(2)O(6))(3)(C(2)H(6)OS)(2)](n), exists as a linear chain along [111] as the three dinitro-benzoate anions each engages in bridging adjacent dimethyl sulfoxide (DMSO) coordinated Ce(III) atoms. The metal atoms are surrounded by eight O atoms in a square-anti-prismatic environment. There are two independent formula units in the asymmetric unit. The S atoms of two of the four DMSO mol-ecules are disordered in a 0.926?(3):0.074?(3) ratio.

Project description:The title compound, [Sr(C(8)H(5)N(2)O(6))(2)(H(2)O)(2)](n), essentially consists of a one-dimensional polymeric network with Sr(2)O(2) rings extending along the [100] direction. The range of Sr-O bond lengths is 2.4822 (13)-2.8113 (13) Å. C-H⋯O and O-H⋯O hydrogen-bonding inter-actions stabilize the mol-ecules in the form of a two-dimensional polymeric network parallel to (001). One of the nitro groups is disordered over three sets of sites with the occupancy ratio of 0.46:0.32:0.22.

catena-Poly[bis-(?(3)-2-methyl-3,5-dinitro-benzoato)disilver(I)].

Project description:In the title coordination polymer, [Ag(2)(C(8)H(5)N(2)O(6))(2)](n), the silver ion is coordinated to three O atoms from three different anions in an approximate T-shape with one bond much longer than the other two. The polyhedral connectivity leads to [100] chains containing alternating centrosymmetric four-rings and eight-rings, with a short d(10)?d(10) Ag?Ag interaction [2.8846?(4)?Å] across the latter. The nitro groups are oriented at dihedral angles of 21.2?(5) and 64.3?(3)° with respect to the aromatic ring of the ligand. A C-H?O inter-action occurs in the crystal.

Poly[(?-3,5-dinitro-benzoato)(?-3,5-dinitro-benzoic acid)rubidium].

Project description:The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(6))(C(7)H(4)N(2)O(6))](n), comprises an Rb(+) cation, a 3,5-dinitro-benzoate anion and a 3,5-dinitro-benzoic acid ligand. The Rb(+) cation is nine-coordinated by O atoms from four 3,5-dinitro-benzoate anions and three neutral 3,5-dinitro-benzoic acid ligands. The metal atom is firstly linked by four bridging carboxyl groups, forming a binuclear motif, which is further linked by the nitro groups into a two-dimensional framework along the [110] direction. A short O-H?O hydrogen bond between two adjacent carboxy/carboxylate groups occurs.

Project description:In the title mononuclear complex, [Sn(CH(3))(3)(C(7)H(5)N(2)O(6))(C(2)H(6)OS)], the Sn(IV) ion is coordinated by three methyl groups in the equatorial plane, and by an O atom from a 2-methyl-3,5-dinitrobenzoate ligand and a dimethyl sulfoxide ligand in the axial sites, to form a slightly distorted trigonal-bipyramidal environment. The O atoms of one of the nitro groups are disordered over two sets of sites, with refined occupancies of 0.55?(4) and 0.45?(4). The closest inter-molecular inter-action is a weak C-H?O hydrogen bond.

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.

Project description:The title compound, {[Cd(C(19)H(13)N(4)O(4))(2)(H(2)O)(2)]·4H(2)O}(n) or {[Cd(BBA)(2)(H(2)O)(2)]·4H(2)O}(n), where BBA is 3,5-bis-(iso-nicotin-amido)-benzoate, is isotypic with its Mn isologue [Chen et al. (2009 ▶). J. Coord. Chem.62, 2421-2428]. The cation sits on a twofold axis and is six-coordinated in a slightly distorted octa-hedral geometry; the polyhedra are linked into zigzag chains, which are further connected by N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds as well as π-π inter-actions [centroid-centroid distance of 3.639 (2) Å], giving a three-dimensional supra-molecular framework.

Poly[(?(6)-2-methyl-3,5-dinitro-benzoato)potassium].

Project description:In the structure of the title coordination polymer, [K(C(8)H(5)N(2)O(6))](n), each ligand bridges six K(+) cations. The carboxyl-ate group coordinates both bidentately to one K(+) ion and monodentately to two K(+) ions, while one nitro group coordinates bidentately to a fourth K(+) ion. The last two K(+) ions are coordinated by the remaining nitro group, one in a bidentate fashion, the other monodentately through one O atom. This bridging mode results in a three-dimensional network. The coordination geometry of the K(+) ion is represented by an irregular KO(9) polyhedron. Very weak C-H?O inter-actions are observed in the crystal structure.

A pair of bis(3,5-dimethyl-1H-pyrazol-4-yl) selenide (L) ligands bridges the copper centers into a polymeric chain extending along [001]. The perchlorate anions are involved in inter-molecular N-H?O hydrogen bonding, which links the chains into layers parallel to the bc plane.

Project description:The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(6))](n), comprises an Rb cation and a 3,5-dinitro-benzoate anion.

The metal atom is firstly linked by the carboxyl-ate groups into a chain along the c-axis direction, which is further linked by bonds between the Rb and nitro O atoms, giving a three-dimensional framework.
