The reaction of anhydrous lanthanide chlorides together with 4,4'-bipyridine yields the MOFs 2∞[Ln2Cl6(bipy)3]·2bipy, with Ln = Pr - Yb, bipy = 4,4'-bipyridine, and 3∞[La2Cl6(bipy)5]·4bipy. Post-synthetic thermal treatment in combination with different vacuum conditions was successfully used to shape the porosity of the MOFs. In addition to the MOFs microporosity, a tuneable mesoporosity can be...

The title compound, [Mg(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(4)FO(2))(2), consists of a bivalent [Mg(C(10)H(8)N(2))(H(2)O)(4)](2+) cation and two 4-fluorbenzoate anions. In the complex cation, the Mg(II) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and four water O atoms in a distorted MgN(2)O(4) octa-hedral geometry. The Mg(II) atom is located on a twofold rotation axis and thus...

Pillared-layer type 3D porous coordination polymers with 2-sulfonylterephthalate, 4,4'-bipyridine and Zn(2+) have metal-free sulfonate groups on the pore walls, providing Lewis basic property for acid guest sorption.

Complexes of Co(iii) containing mixed chelating diimine and o-quinone ligand sets are of fundamental interest on account of their fascinating magnetic and electronic properties. Whilst complexes of this type containing one diimine and two o-quinone ligands have been studied extensively, those with the reverse stoichiometry (two diimines and one o-quinone) are much rarer. Herein, we describe a r...

In the polymeric title complex, [Mn(C(9)H(9)O(2)S)(2)(C(10)H(8)N(2))(H(2)O)(2)](n), the Mn(2+) cation and the 4,4'-bipyridine ligand lie on a twofold rotation axis. The cation has an MnN(2)O(4) octa-hedral environment, being coordinated by the O atoms of two water mol-ecules and two monodentate (4-tolyl-sulfan-yl)acetate anions, and by two N atoms of two 4,4'-bipyridine ligands. The latter brid...

The asymmetric unit of title compound, [Cd(C(9)H(6)NO(2))(2)(C(10)H(8)N(2))(2)]·0.5C(10)H(8)N(2)·2H(2)O, consists of one complex mol-ecule, one half of an uncoordinated 2,2'-bipyridine mol-ecule and two solvent water mol-ecules. The uncoordinated 2,2'-bipyridine mol-ecule is located on a center of symmetry. Within the complex mol-ecule, the Cd(II) atom is coordinated by four N atoms from two 2,...

We report the successful use of Ru(II)(terpy)(2) (1, terpy = 2,2':6',2''-terpyridine) as a catalyst in the Belousov-Zhabotinsky (BZ) oscillating chemical reaction. We also examine several additional Ru(II) complexes, Ru(II)(bipy)(2)(L')(2) (2, L' = 4-pyridinecarboxylic acid; bipy = 2,2'-bipyridine) and Ru(II)(bipy)(2)(L'') (3, L'' = 4,4'-dicarboxy-2,2'-bipy; 4, L'' = N-allyl-4'-methyl-[2,2'-bip...

We report new divalent osmium complexes that feature strong red metal-to-ligand-charge-transfer (MLCT) phosphorescence and electrophosphorescence. The general formula of the complexes is Os(II)(N-N)(2)L-L, where N-N is either a bipyridine or a phenanthroline and L-L is either a phosphine or an arsine. New polypyridyl ligands synthesized are 4,4'-di(biphenyl)-2,2'-bipyridine (15) and 4,4'-di(dip...

The title complex, [Pt(CH(3))(2)(SCH(2)CH(2)CO(2))(C(10)H(8)N(2))], is formed by the unusual oxidative addition of the disulfide, R(2)S(2) (R = CH(2)CH(2)CO(2)H), to (2,2'-bipyridine)-dimethyl-platin-um(II) with elimination of RSH. The product contains an unusual six-membered thiol-ate-carboxyl-ate chelate ring. This slightly distorted octa-hedral complex exhibits cis angles ranging from 77.55 ...
