Heterotetrametallic [{[Ti](μ-σ,π-C≡CSiMe3)2}Cu-bipy-C≡C-AuPh2PFc]PF6 (5) ([Ti] = (ηC5H4SiMe3)2Ti; Fc = (η-C5H4)(η-C5H5)Fe; bipy = 2,2`-bipyridine) is accessible by the consecutive reaction of FcPPh2-AuCl (1) with 5-ethynyl-2,2`-bipyridine (2) producing FcPPh2-AuC≡C-bipy (3) which further reacts with [{[Ti](μ-σ,π-C≡CSiMe3)2}Cu(N≡CMe)]PF6 (4) to give the title complex in which four different tran...

A propyltrimethoxysilane-modified 2,2'-bipyridine ligand is synthesized and its acetonitrile solutions are used to prepare monolayers of the molecule on glass surfaces. Absorption and X-ray photoelectron spectroscopy demonstrate that the modified glass surfaces bind Cu(2+) with a 1:1 ratio with respect to the 2,2'-bipyridine moieties under the chosen preparative conditions, producing materials ...

In the title complex, [Zn(C(7)H(5)O(3))(2)(C(10)H(8)N(2))(H(2)O)], the Zn(II) ion is coordinated by two 4-hydroxy-benzoate anions, one 2,2'-bipyridine mol-ecule and one water mol-ecule and displays a distorted octa-hedral geometry. One Zn-O bond [2.5300 (15) Å] is much longer than the others in the mol-ecule. In the crystal structure, the face-to-face separation of 3.547 (9) Å suggests no π-π s...

In the title co-crystal, C(10)H(8)N(2)·2C(5)H(7)NO(3), the 4,4'-bipyridine mol-ecule [dihedral angle between the pyridine rings = 36.33 (11)°] accepts O-H⋯N hydrogen bonds from the two pyroglutamic (pga) acid mol-ecules. The pga mol-ecules at each end of the trimeric aggregate self-associate via centrosymmetric eight-membered amide {⋯HNCO}(2) synthons, so that the crystal structure comprises on...

The synthesis and characterization of four iridium(iii) complexes [Ir(thpy)2(N^N)][PF6] where Hthpy = 2-(2'-thienyl)pyridine and N^N are 6-phenyl-2,2'-bipyridine (1), 4,4'-di-(t)butyl-2,2'-bipyridine (2), 4,4'-di-(t)butyl-6-phenyl-2,2'-bipyridine (3) or 4,4'-dimethylthio-2,2'-bipyridine (4) are described. The single crystal structures of ligand 4 and the complexes containing the [Ir(thpy)2(1)](...

The asymmetric unit of the title compound, C(10)H(8)N(2)·C(8)H(7)NO(4), contains two half-mol-ecules, which constitute a 1:1 co-crystal. The 2-amino-terephthalic acid mol-ecule is situated on an inversion center being disordered between two orientations in a 1:1 ratio. In the 4,4'-bipyridine mol-ecule, which is situated on a twofold rotational axis, the two pyridine rings form a dihedral angle ...

The title compound, C(10)H(8)N(2)·2C(7)H(5)NO(4),was obtained unintentionally as the harvested product of the hydro-thermal reaction between Co(OAc)(2)·4H(2)O and 4,4'-bipyridine in the presence of 3-nitro-phthalic acid. In the reaction, 3-nitro-phthalic acid is transformed into 3-nitro-benzoic acid by an in situ deca-rboxylation reaction, in which the carboxyl-ate group is not deprotonated and...

A new binuclear complex of [{NiCl(6-mbipy)}2(μ-Cl)2] (1) was prepared from the reaction of NiCl2.6H2O and 6-methyl-2,2'-bipyridine (6-mbipy)  in a mixture of methanol and acetonitrile. Suitable crystals of 1 for X-ray diffraction measurement were obtained by slow evaporation of the resulted green solution at room ...

We report the synthesis of free 1,6,7,12-tetraazaperylene (tape). Tape was obtained from 1,1'-bis-2,7-naphthyridine by potassium promoted cyclization followed by oxidation with air. Mono- and dinuclear ruthenium(II) 1,6,7,12-tetraazaperylene complexes of the general formulas [Ru(L-L)(2)(tape)](PF(6))(2), [1](PF(6))(2)-[5](PF(6))(2), and [{Ru(L-L)(2)}(2)(μ-tape)](PF(6))(4), [6](PF(6))(4)-[10](PF...
