Poly[(?-2-hy-droxy-3,5-dinitro-benzoato)rubidium].

ABSTRACT: The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(7))](n), comprises an Rb(+) cation and a 3,5-dinitro-salicylate ligand. The Rb(+) cation is 10-coordinated by O atoms from eight 3,5-dinitro-salicylate anions and is linked by three ?(2)-O atoms, forming a zigzag chain along the b-axis direction, which is further linked by the phenyl groups, giving the three-dimensional framework. The crystal structure involves intra-anionic O-H?O hydrogen bonds and strong ?-? stacking inter-actions [centroid-centroid distance = 3.6755?(7)?Å].

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: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 Rb cation is eight-coordinated by O atoms from five 3,5-dinitro-benzoate anions. On the other hand, each 3,5-dinitro-benzoate anion links five Rb cations with the carboxyl-ate groups as ?(3)-bridging. 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.

catena-Poly[(diaqua-strontium)-bis-(μ-2-methyl-3,5-dinitro-benzoato)].

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.

Poly[aqua-(?(3)-2-hy-droxy-5-nitro-benzoato-?O:O:O)rubidium].

Project description:In the structure of title compound, [Rb(C(7)H(4)NO(5))(H(2)O)](n), the centrosymmetric cyclic dimeric repeating unit comprises two irregular RbO(4) complex centres bridged by the carboxyl-ate groups of the 5-nitro-salicylate ligands. The coordination about each Rb atom is completed by a monodentate water mol-ecule and a phenolic O-atom donor which gives a bridging extension [Rb-O range = 3.116?(7)-3.135?(5)?Å]. The polymeric structure is stabilized by inter-molecular water O-H?O(carboxyl-ate) hydrogen bonds and weak inter-ring ?-? inter-actions [minimum ring centroid separation = 3.620?(4)?Å]. An intramolecular O-H?O hydrogen bond between phenol and carboxylate groups is also present.

Project description:In the title molecular salt, C(6)H(8)NO(+)·C(7)H(3)N(2)O(6) (-), which crystallizes in the chiral monoclinic space group P2(1), the achiral components assemble by three different N-H⋯O, one O-H⋯O and one C-H⋯O hydrogen bonds into two-stranded chains running parallel to [010]. The dihedral angles between the carboxy group and the two nitro groups and the mean plane of their attached benzene ring are 24.5 (9), 6.1 (6) and 13.0 (1)°, respectively..

Poly[μ(3)-aqua-μ(2)-2,4-dinitro-phenolato-rubidium(I)].

Project description:The asymmetric unit of the title compound, [Rb(C(6)H(3)N(2)O(5))(H(2)O)](n), comprises a rubidium cation, a 2,4-dinitro-phenoxide anion and a water mol-ecule. The Rb(+) cation is 11-coordinated by O atoms from 2,4-dinitro-phenolate anions and water mol-ecules. The metal centre is firstly coordinated by two μ(3)-H(2)O to form a one-dimensional ladder-shaped unit, [Rb(2)(μ(3)-H(2)O)(2)], which is further linked by 2,4-dinitro-phenolate to give the three-dimensional framework of the title compound. The crystal structure involves O-H⋯O hydrogen bonds.

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.

Project description:In the anion of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the two nitro groups are twisted from the attached benzene ring with dihedral angles of 27.36?(10) and 4.86?(11)°.

In the crystal, the cations and anions are linked by N-H?O and C-H?O inter-actions and are further consolidated by C-H?? inter-actions, to generate a three-dimensional network. A short O?N contact of 2.876?(2)?Å also occurs.

A two-dimensional manganese(II) complex: poly[bis-(μ(2)-4,4'-bipyrid-yl)tetra-kis-(μ(2)-3,5-dinitro-benzoato)dimanganese(II)].

Project description:The Mn atom in the title compound, [Mn(2)(C(7)H(3)N(2)O(6))(4)(C(10)H(8)N(2))(2)](n), is six-coordinated by two N atoms and four O atoms, forming a distorted octa-hedral geometry. The Mn-O bond lengths are in the range 2.1281 (13)-2.2011 (12) Å and the Mn-N bond lengths are 2.269 (2) and 2.278 (2) Å. Mn(II) atoms are double-bridged along the a axis by two pairs of bi-monodentate carboxyl groups, forming a double-stranded chain, while the bidentate 4,4'-bipyridine ligand bridges the Mn atom along the b axis. This results in a two-dimensional structure constructed of oblong grids with the sides of length 11.634 and 5.075 Å
