By solvent free syntheses of the rare earth trichlorides LnCl(3), Ln = Pr, Nd, Sm, Eu, Tb with melts of 4,4'-bipyridine two-dimensional frameworks of the formula (2)(infinity)[Ln(2)Cl(6)(4,4'-bipy)(3)] x 2(4,4'-bipy) are obtained, with 4,4'-bipy = C(10)H(8)N(2), 4,4'-bipyridine. 4,4'-Bipyridine acts both as a linker ligand as well as a template and populates all cavities in the structures. The ...

Tow new compound of type [(chelate)2Cu-OH-Cu(chelate)2] X3.nH2O, where chelate=1,10-phenanthroline; X=Cl¯(n=3.5) and chelate=4,4'-dimethyl-2,2'-bipyridine;  (n=5) have been synthesized and their properties investigated. The complexes show room temperature magnetic moment order of 1.0 B.M. per copper atom. The X-band ESR spectrum of powdered sample...

There are three tables for this electrochemical series. Each table lists standard reduction potentials, E° values, at 298.15 K (25 °C), and at a pressure of 101.325 kPa (1 atm). Table 1 is an alphabetical listing of the elements, according to the symbol of the elements. Thus, data for silver (Ag) precede those for aluminum (Al). Table 2 lists only those reduction reactions that have E° values p...

Seven new hetero triply-bridged dinuclear Cu(II) compounds have been synthesized and characterized corresponding to a series with general formula [Cu(2)(L)(2)(μ-OH)(μ-OH(2))(μ-O(2)CR)]X(2) (where L = bpy = 2,2'-bipyridine, 4,4'-dmbpy = 4,4'-dimethyl-2,2'-bipyridine and 5,5'-dmbpy = 5,5'-dimethyl-2,2'-bipyridine; R = H for formate, CH(3) for acetate, CH(2)CH(3) for propionate and C(CH(3))(3) for...

The reaction of 2-hy-droxy-1,4-naphtho-quinone and 4,4'-bipyridine with zinc acetate produced the title compound, [Zn(C(10)H(5)O(3))(2)(C(10)H(8)N(2))(H(2)O)]·C(10)H(8)N(2)·2H(2)O. The bond lengths and angles around the metal atom indicate a deviation from octa-hedral geometry. The two naphtho-quinone ligands coordinate in a cis fashion, with the 4,4'-bipyridine ligand and the water mol-ecules ...

The title complex, [Cd(C(2)HN(9))(C(10)H(8)N(2))(2)]·0.5C(10)H(8)N(2)·H(2)O, was prepared under hydro-thermal reaction conditions. The asymmetric unit contains the cadmium complex, half a 2,2'-bipyridine solvent mol-ecule and a solvent water mol-ecule. The Cd(II) ion is coordinated by four N atoms from two 2,2'-bipyridine ligands and two N atoms from an HBTA(-) anion ligand [where H(2)BTA is N,...

The synthesis of three new homoleptic trischelate ruthenium(ii) complexes bearing new 2,2'-bipyridine ligands, 5,5'-dibenzylamido-2,2'-bipyridine () and 5-benzylamido-2,2'-bipyridine (L1) has been achieved. In the case of [Ru(L2)(3)](2+), the mer and fac isomers have been separated. (1)H NMR spectroscopic anion binding studies indicate that the two C(3)-symmetric pockets provided by [Ru(L1)(3)]...

In the title compound, K[Co(CO(3))(2)(C(10)H(8)N(2))]·2H(2)O, the Co(III) atom is coordinated by two bipyridine N atoms and four O atoms from two bidentate chelating carbonate anions, and thus adopts a distorted octa-hedral N(2)O(4) environment. The [Co(bipy)(CO(3))(2)](-) (bipy is 2,2'-bipyridine) -units are stacked along [100] via π-π stacking inter-actions, with inter-planar distances betwee...

A series of alkynylcarbyne(bipyridine)(dicarbonyl)trifluoroacetato complexes, [CF3COO(L /L)(CO)2M /C /C /C /R] (M /W, Mo; L /L /2,2?-bipyridine, 4,4 ?-dimethyl 2,2 ?-bipyridine; R /SiMe3, Ph, p -Tol, t -Bu), has been prepared by sequential reaction of [M(CO)6] with Li[C /CR], trifluoroacetic anhydride, and L /L. All complexes were fully characterized. Concentrated solutions of these complexes e...
