A series of novel, dinuclear (2,2':6',2''-terpyridine)platinum(ii) complexes containing bis(thioalkyl)-dicarba-closo-dodecaborane(12)(carborane) ligands were prepared and characterised, and their preliminary anti-cancer characteristics have been determined in vitro; the complexes are the first examples of bis-intercalator complexes containing a boron-rich carborane cage.

The self-assembly of supramolecular structures depends on a subtle interplay of a series of different control mechanisms. The geometric as well as electronic complementarity of the molecular building blocks is crucial for the specific formation of defined supramolecular species. In addition, secondary effects, like templating, also have an important function. The templating ability of different...

The reaction of [(AuBr)2(μ-PR2P(CH2)nPR2)] (where R ) CH3 for n ) 1; R ) Ph for n ) 1, 3, 4) with N-alkylxanthine and thioxanthine derivatives, containing two ionizable protons in close positions, yields, under basic conditions, neutral heterobridged dinuclear gold(I) ring complexes [Au(μ-L)2(μ-PR2P(CH2)nPR2)], which have been investigated by means of 1Hand 31P-NMR and FAB spectroscopies. Cryst...

The crystal structure of the dinuclear arene ruthenium title complex, [Ru2(C6H5OS)(C7H7S)2(C10H14)2]BF4, shows the two Ru(II) atoms to be bridged by two benzyl-thio-pheno-late units and one 4-hy-droxy-thio-pheno-late unit, with the remaining three coordination sites of each Ru(II) atom being occupied by p-cymene ligands, completing the typical piano-stool coordination geometry. The BF4 (-) coun...

Neutral dinuclear dithiolato-bridged pentamethylcyclopentadienyl Rh(III) complexes of the type (C5Me5)2Rh2(μ-SR)2Cl2 (R = CH2Ph, 1; R = CH2CH2Ph, 2) and cationic dinuclear trithiolato-bridged pentamethylcyclopentadienyl Rh(III) and Ir(III) complexes of the type [(C5Me5)2M2(μ-SR)3](+) (M = Rh, R = CH2Ph, 3; M = Rh, R = CH2CH2Ph, 5; M = Rh, R = CH2C6H4-p-(t)Bu, 7: M = Ir, R = CH2Ph, 4; M = Ir, R ...

Reactions of 0.5 eq. of the dinuclear complexes [(g-arene)Ru(l-Cl)Cl]2 (arene = g-C6H6, g-p-PrC6H4Me) and [(Cp*)M(l-Cl)Cl]2 (M = Rh, Ir; Cp* = g-C5Me5) with 4,6-disubstituted pyrazolyl-pyrimidine ligands (L) viz. 4,6-bis(pyrazolyl)pyrimidine (L1), 4,6-bis(3-methyl-pyrazolyl)pyrimidine (L2), 4,6-bis(3,5dimethyl-pyrazolyl)pyrimidine (L3) lead to the formation of the cationic mononuclear complexes...

A biphenyl-linked bis-β-diketone ligand, 3,3'-bis(3-phenyl-3-oxopropanol)biphenyl (BPB) has been prepared for the syntheses of a series of dinuclear lanthanide complexes. The ligand bears two benzoyl β-diketonate sites linked by a 3,3'-biphenyl spacer. Reaction of the doubly negatively charged bis-bidenate ligand with lanthanide ions forms triple-stranded dinuclear complexes Ln(2)(BPB)(3) (Ln=N...

Two new AIE-active dinuclear Schiff base Ir(III) complexes exhibit highly reversible piezochromic phosphorescence behaviour enabling the construction of a re-writable phosphorescence data recording device.

The mono- (1) and dinuclear (2) ruthenium(II) bis(2,2'-bipyridine) complexes of 2,5-di(pyridin-2-yl)pyrazine (2,5-dpp), for which the UV/Vis absorption and emission as well as electrochemical properties have been described earlier, are reinvestigated here by resonance, surface enhanced and transient resonance Raman spectroscopy together with selective deuteration to determine the location of th...
