To achieve a reliable radiocarbon (14C) date for an object, any contamination that may be of a different age must be removed prior to dating. Samples that have been conserved with treatments such as adhesives, varnishes or consolidants can pose a par
The triple decker dinuclear Cr(ii) salt [(η5-C 5Me5)Cr(μ2:η5-P 5)Cr(η5-C5Me5)]+ (SbF6)- has been structurally characterised by multiple temperature X-ray diffraction experiments from 290 K to 12 K. This material shows changes in its structural fe

Slow reactions of isomeric metallacarboranes of general formulae [(NMe2)3TaC2B9H11] (3 isomers) and [(NMe2)3TaC2B9H10Me] (3 isomers) with CD2Cl2 afford quantitative yields of monochloro complexes [Cl(NMe2)2TaC2B9H11] and [Cl(NMe2)2TaC2B9H10Me]. Expos

The cage-alkylated metallacarborane complex [4,4,4-(NMe2)3-3-Me-4,1,2-closo-TaC2B9H10] 8, is obtained as the only product from the reaction of Ta(NMe2)5 with nido-11-Me-2,7-C2B9H124, which is prone to skeletal rearrangement under basic conditions. Th

The amine elimination reaction of W(NtBu)2(NHtBu)2 with the di-basic carborane acid nido-7,8-C2B9H13 generates the tungsten(VI) carborane complex, [W(NtBu)(NHtBu)2(C2B9H11)] 1, in which a C2B9H11 ligand has replaced one imido ligand. One of the remai

The reaction of Li[1-tBuMe2Si-1,2-C2B10H10] with N-(bromoethyl)phthalimide or N-3-(bromopropyl)phthalimide generates unusual carboranyl heterocycles, resulting from nucleophilic substitution followed by insertion of a phthalimide carbonyl into the C
