The reaction of lead acetate, 4-hydroxy-benzoic acid and 2,2'-bipyridine in aqueous solution gave the title complex, [Pb(C(7)H(5)O(3))(2)(C(10)H(8)N(2))]·H(2)O. The asymmetric unit contains one Pb(II) atom, two 4-hydroxy-benzoate ligands, one 2,2'-bipyridine ligand and one uncoordinated water mol-ecule. The Pb(II) atom is hexa-coordinated in a distorted tetra-gonal-bipyramidal geometry and is c...

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...

A series of cationic metalla-rectangles of the general formula [(p-cymene)(4)Os(4)(OO[intersection]OO)(2)(N[intersection]N)(2)](4+) have been obtained in methanol from the dinuclear arene osmium precursors [(p-cymene)(2)Os(2)(OO[intersection]OO)(2)Cl(2)] (OO[intersection]OO = 2,5-dioxydo-1,4-benzoquinonato (dhbq), 2,5-dichloro-1,4-benzoquinonato (dcbq)) by reaction with bipyridine linkers (N[in...

N -tert -butyliminodiacetic acid (H2TEBIDA, compound 1) has been prepared and characterised by thermogravimetric analysis, FT-IR and NMR spectra, and X-ray crystallography (final R1 /0.04). The zwitterion H2TEBIDA 9 is intra -stabilised by a hydrogen bond, and H-bonded chains of zwitterions form supramolecular 2D bilayers with tert -Bu groups towards the external faces. Compounds [Cu(TEBIDA)(H2...

Reaction of 1-(3-cyanopropoxy)-3,4-dihydronaphthalene-2-carbonitriles with potassium tert-butoxide gave 5-amino-1,2,6,7-tetrahydrobenzo[f]furo[2,3-c]isoquinolines via a Truce-Smiles rearrangement. The 5-amino group was transformed to the bromo derivatives which were allowed to react with aliphatic cyclic amines to produce amino derivatives. In contrast, a combination of imidazole and NaH gave a...

Immobilization of [Mn(bpy)(CO)3Br], (1) and [Mn(bpy((t)Bu)2)(CO)3Br] (2, where (bpy((t)Bu)2) = 4,4'-di-tert-butyl-2,2'-bipyridine) in Nafion/multi-walled carbon nanotubes (MWCNT) on glassy carbon yielded highly active electrodes for the reduction of CO2 to CO in aqueous solutions at pH 7. Films incorporating have significantly improved selectivity towards CO2, with CO : H2 ∼ 1 at -1.4 V vs. SCE...

A new trinuclear Cd (II) complex [Cd3(L)6(2,2-bipyridine)3] [L = N-phenylsulfonyl-L-leucinato] has been synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction analysis. The results show that the complex belongs to the orthorhombic, space group P212121 with a = 16.877(3) Å, b = 22.875(5) Å, c = 29.495(6) Å, α = β = γ = 90°, V = 11387(4) Å, Z = 4, Dc= 1.416 μ...

In the title compound, {[Zn(C(4)H(4)O(5))(C(10)H(8)N(2))]·2H(2)O}(n), the Zn(II) ion displays a distorted tetra-gonal-pyramidal coordination environment with one hy-droxy O and three carboxyl-ate O atoms from three malate anions, and the one remaining position occupied by an N atom from a 4,4'-bipyridine ligand. The pyridine rings of the 4,4'-bipyridine ligand are twisted with respect to each o...
