Bis[?-4-(1H-imidazol-3-ium-1-yl)benzoato-?O:O']bis-[(methanol)tris-(nitrato-?O,O')terbium(III)].

ABSTRACT: In the centrosymmetric dinuclear title complex, [Tb(2)(NO(3))(6)(C(10)H(8)N(2)O(2))(2)(CH(3)OH)(2)], the Tb atoms are bridged by the carboxyl-ate groups of the two 4-(1H-imidazol-3-ium-1-yl)benzoate (iba) ligands. The iba ligand adopts a zwitterionic form with a protonated imidazole group. The Tb atom adopts a distorted tricapped trigonal-prismatic coordination geometry and is coordinated by six O atoms of three chelating nitrate ions, one O atom of the methanol mol-ecule and two O atoms of two iba ligands. The intra-molecular Tb?Tb separation is 5.1419?(3)?Å. O-H?O and N-H?O hydrogen bonds connect complex mol-ecules into a two-dimensional network.

Poly[1H-imidazol-3-ium [di-?-nitrato-sodium]].

Project description:In the title compound {(C3H5N2)[Na(NO3)2]} n , the Na(I) ion is coordinated by eight O atoms from three bidentate nitrate anions and two O atoms from two monodentate nitrate anions, displaying a bicapped trigonal-prismatic geometry. The imidazolium cation is essentially planar (r.m.s. deviation for all non-H atoms = 0.0018?Å). In the crystal, the Na(I) ions are connected by bridging nitrate ligands, forming layers parallel to (010). The imidazolium cations are sandwiched between these layers. Weak C-H?O hydrogen bonds link the layers into a three-dimensional network. In addtion, ?-? inter-actions between the imidazolium rings [centroid-centroid distance = 3.588?(3)?Å] are observed.

Bis(?-2-methyl-quinolin-1-ium-8-olato-?O:O')bis-[(2-methyl-quinolin-1-ium-8-olato-?O)tris-(nitrato-?O,O')lanthanum(III)].

Project description:The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinuclear structure is further stabilized by intra-molecular N-H?O(nitrate) hydrogen bonds.

Tetra-kis(?-4-methoxy-benzoato)bis-[(4-methoxy-benzoato)(1,10-phenan-throline)terbium(III)].

Project description:In the title dinuclear complex, [Tb(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2)], each Tb(III) ion is eight-coordinated by two N atoms from a 1,10-phenanthroline ligand and six O atoms from the carboxyl-ate groups of five 4-methoxy-benzoate ligands in a distorted square-anti-prismatic geometry. All six 4-methoxy-benzoate ligands act in a bidentate mode, two coordinating to one Tb center each and the other four bridging two Tb centers [Tb?Tb separation = 4.3144?(6)?Å]. In the crystal, inter-molecular ?-? inter-actions between the aromatic rings of 1,10-phenanthroline and 4-methoxy-benzoate ligands [centroid-centroid distance = 3.742?(9)?Å] link two mol-ecules into a centrosymmetric dimer. Weak inter-molecular C-H?O hydrogen bonds help to consolidate the crystal packing.

Tetra-kis(μ-2,4-difluoro-benzoato)bis-[(2,2'-bipyridine)(2,4-difluoro-benzoato)terbium(III)].

Project description:In the centrosymmetric dinuclear title compound, [Tb(2)(C(7)H(3)F(2)O(2))(6)(C(10)H(8)N(2))(2)], the Tb(III) ion is coordinated by an N,N'-bidentate 2,2'-bipyridine mol-ecule, and two O,O'-bidentate 2,4-difluoro-benzoate (dfb) anions. One of the latter also bonds to the second Tb(III) centre through one of its O atoms. The third dfb anion bonds to one Tb atom from each of its O atoms. Thus, the three dfb species have three different coordination modes. This results in an irregular TbN(2)O(7) coordination sphere for the metal ion. The F atoms and their associated H atoms in the simple bidentate dfb anion are disordered over two sets of sites in a 0.672 (10):0.328 (10) ratio.

Project description:In the title compound, [Cd(NO3)2(C8H7N3)2(H2O)2], the Cd(II) cation is situated on an inversion center and is coordinated by the O atoms of two nitrate anions, by the N atoms of two 4-(imidazol-2-yl)pyridine ligands and by two water O atoms in a slightly distorted N2O4 octa-hedral geometry. The dihedral angle between the imidazole and pyridine rings is 1.6?(2)°. In the crystal, mol-ecules are linked by N-H?O, O-H?N and O-H?O hydrogen bonds, forming a three-dimensional network.

Project description:The title dinuclear compound, [Tb(2)(C(7)H(5)O(3))(6)(H(2)O)(6)]·10H(2)O, lies on a center of inversion and the two Tb(III) atoms are bridged by two 4-hydroxy-benzoate anions; each metal atom is further coordinated by one monodentate anion and chelated by the third anion. The eight-coordinate geometry approximates a square anti-prism. Hydrogen bonds of the O-H⋯O type connect the uncoordinated water mol-ecules to the dinuclear species, forming a three-dimensional network.

Tris(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')holmium(III).

Project description:In the title compound, [Ho(NO(3))(3)(C(12)H(8)N(2))(2)], the ten-coordinate Ho(III) ion is chelated by four N atoms from two phenanthroline (phen) ligands and six O atoms from three bidentate nitrate groups. The environment around the Ho atom can be described as a distorted bicapped square anti-prism. Two phenanthroline ligands form a dihedral angle of 43.72 (13)°. Short inter-molecular distances between the centroids of the six-membered rings [3.6887 (14)-3.8374 (16) Å] indicate the existence of π-π inter-actions, which link the mol-ecules into stacks extended in the [10] direction. The crystal packing is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
