The reaction of [Ag(MeCN)(4)]ClO(4) with N,N,N',N'-tetra(diphenylphosphanylmethyl)ethylenediamine (dppeda) in CH(2)Cl(2)/MeOH afforded an unexpected cationic binuclear complex [Ag(2)(L(1))(2)(η,η-μ-ClO(4))(2)](ClO(4))(2) (L(1) = N,N'-bis(diphenylphosphanylmethyl)-3H-4,5-dihydroimidazole-1-ium) (1). Compound 1 was also prepared in high yield from reactions of [Ag(MeCN)(4)]ClO(4) with N,N'-bis(di...

The amidinato complexes o f silver(I) and gold(I), M 2[P h-C (N SiM e3)2]2, have been prepared by the reaction o f N,N,N'-tris(trimethylsilyl)benzamidine with A g 0 2CCH3, and ClAuCO, re­ spectively, in acetonitrile suspensions. Both complexes were characterized by IR spectroscopy as well as by X-ray structure determinations. Ag-,[Ph-C(NSiM e3)2]-,: Space group P I, Z = 2 (6408 observed unique ...

Spectroelectrochemical sensing a metal in two different oxidation states, both of which are weakly absorbing in the visible wavelength range, was demonstrated with ferrous and ferric ion. The sensor consisted of an indium tin oxide optically transparent electrode (ITO OTE) coated with a thin film of Nafion preloaded with the ligand 2,2'-bipyridine (bipy). Fe2+ in the sample partitioned into the...

1,3-Bis(3'-butylimidazol-1'-yl)benzene diiodide (2a), 1,3-bis(3'-but-3''-enyl-imidazolium-3'-yl)benzene diiodide (2b), 1,3-bis(3'-pent-4''-enyl-imidazolium-3'-yl)benzene diiodide (2c), 1,3-bis(4'-butyl-1',2',4'-triazolium-1'-yl)benzene diiodide (2d), or 1,3-bis(4'-butyl-1',2',4'-triazolium-1'-yl)benzene dibromide (2e) was reacted with Ag2O yielding unprecedented tetra-N-heterocyclic carbene-Ag(...

Six supramolecular complexes incorporating benzil as a guest, CMCR*bipy*benzil (alpha) 1 (CMCR = C-methylcalix[4]resorcinarene), CMCR*bipy*benzil (beta) 2, CMCR*2bpe*benzil*ethanol 3 (bpe = trans-1,4-bis(pyridyl)ethylene), CMCR*2bpe*benzil*2H2O 4, CMCR.2bpeh*benzil*ethanol 5 (bpeh = bis-(1-pyridin-4-yl-ethylidene)-hydrazine), and CECR*2bpe.benzil 6 (CECR = C-ethylcalix[4]resorcinarene), have be...

In the title complex, {[Zn(C(10)H(8)N(2))(H(2)O)(4)](C(10)H(6)O(6)S(2))}(n), the [Zn(4,4'-bipy)(H(2)O)(4)](2+) (4,4'-bipy is 4,4'-bipyridine) cations are linked into linear chains along [001] by the 4,4'-bipy ligands. The Zn(II) ion exhibits a slightly distorted octa-hedral coordination geometry in which the four water mol-ecules are in the equatorial positions. The anions are hydrogen bonded t...
