The title compound, [Yb(2)(CF(3)O(3)S)(C(10)H(15))(2)(OH)(2)(C(12)H(12)N(2))(2)](C(24)H(20)B)·C(12)H(12)N(2), crystallizes as a half-sandwich complex with a bridging trifluoro-methane-sulfonate as well as two bridging hydroxide groups. The bound bipyridine ligands have N-C-C-N torsion angles of 13.1 (9) and -12.1 (8)°. The structure also contains an uncoordinated 5,5'-dimethyl-2,2'-bipyridine molecule with an N-C-C-N torsion angle of 169.5 (7)°. The triply bridged Yb centers are 3.5990 (4) Å apart. The Yb-N bond lengths are in the range 2.389 (6)-2.424 (5) Å.

In the title compound, [Cu(C(14)H(8)O(5))(C(12)H(12)N(2))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. Two N atoms of the chelating 5,5'-dimethyl-2,2'-bipyridine (dbp) ligand and two O atoms of two different 2,2'-oxydibenzoic (odb) ligands occupy the basal plane while the water O atom completes the square-pyramidal geometry at the apical site. The non-water N(...

In the crystal of the title polymeric compound, [CdBr(2)(C(12)H(12)N(2))](n), the Cd(II) cation is located on a twofold rotation axis. The Cd(II) cation is six-coordinated in a distorted octa-hedral geometry formed by two N atoms from the 5,5'-dimethyl-2,2'-bipyridine ligand and four bridging Br(-) anions. The bridging function of the Br(-) anions leads to a polymeric chain running along the c ...

The asymmetric unit of the title compound, [CdCl(2)(C(12)H(12)N(2))](n), contains one half-mol-ecule; a twofold rotation axis passes through the Cd atom. The Cd(II) atom is six-coordinated in a distorted octa-hedral configuration by two N atoms from 2,2'-bipyridine-5,5'-dimethyl and four bridging Cl atoms. The bridging function of the chloro atoms leads to a one-dimensional chain structure. The...
