Cationic calix[6]arene and calix[4]arene derivatives non-covalently bind into a DNA minor groove or RNA major form tweezer-like complexes with nucleotides.
The coordination polymers [Ag4 (O2 CCF3 )4 (phen)3 ]⋅ phen⋅arene (1⋅phen⋅arene) (phen=phenazine; arene=toluene, p-xylene or benzene) have been synthesised from the solution phase in a series of arene solvents and crystallographically characterised. By contrast, analogous syntheses from o-xylene and m-xylene as the solvent yield the solvent-free coordination polymer [Ag4 (O2 CCF3 )4 (phen)2 ] (2...
[RuCl(arene)(μ-Cl)]2 dimers were treated in a 1:2 molar ratio with sodium or thallium salts of bis- and tris(pyrazolyl)borate ligands [Na(Bp(Br3))], [Tl(Tp(Br3))], and [Tl(Tp(iPr, 4Br))]. Mononuclear neutral complexes [RuCl(arene)(κ(2)-Bp(Br3))] (1: arene=p-cymene (cym); 2: arene=hexamethylbenzene (hmb); 3: arene=benzene (bz)), [RuCl(arene)(κ(2)-Tp(Br3))] (4: arene=cym; 6: arene=bz), and [RuCl(...

The effects of introducing bpy ligands with CH 2 CCH substituents in the 6- and 6,6′-positions [Cu(N^N)(P^P)] + complexes are explored; structural data discussed terms CC⋯π arene interactions compounds Cambridge Structural Database.
The nature and energies of the (arene)2Cr, (arene)2V and (arene)2Cr(+) (arene = η(6)-C6H6, η(6)-C6H5Me, η(6)-1,3-C6H4Me2, and η(6)-1,3,5-C6H3Me3) electronic excited states have been determined on the basis of the time-dependent density functional theory (TD DFT) approach and comparison with the gas-phase and condensed-phase absorption spectra. Both valence-shell and Rydberg electronic excitatio...
The reaction of [(arene)RuCl2]2 (arene /C6H6, p -Me /C6H4 / i Pr, C6Me6) with p -thiocresol, 2-mercaptoethanol and p mercaptophenol in refluxing ethanol gives the tris-thiolato complexes [(arene)2Ru2(SR)3] (R /p -C6H4 /Me, CH2CH2OH, p C6H4OH) which can be isolated as the chloride salts. The remarkable selectivity of (arene)ruthenium units for SH versus OH functions reflects the affinity of ruth...
Driven by an interest in the impact of para-substituent calix[4]arenes on metal complexation and structural chemistry, studies p-cyclohexylcalix[4]arene (L) have been carried out. The 1:1 dichloromethane dimethylformamide solvates were found to be isostructural, different typical bilayer structure often observed for p-t-butylcalix[4]arene solvates. methanol solvate, contrast, does form a bilaye...
