The winners of this year’s Dalton Division Awards have now been announced in this month’s RSC News (please see Page 10 in July 01, 2011 issue of RSCNews)

Congratulations to Professor James Cowan (Bioinorganic Chemistry Award), Dr Elizabeth New (Dalton Young Researchers Award), Professor David Parker (Ludwig Mond Award), Dr Stephen Liddle (Sir Edward Frankland Fellowship), Professor Jonathan Williams (Homogeneous Catalysis Award) and Dr Lawrence Que (Inorganic Mechanisms Award).

More about Dalton Division can be found at their website, or on their MyRSC group.

Dalton Transactions new Associate Editor Dan Mindiola, from Indiana University in the USA, has had his recent research highlighted in Chemistry World. His paper, published in Chemical Science, uses a metal-carbon multiple bond complex to activate methane.

The outside cover features work from the Leznoff group.  Four new [AuBr₂(CN)₂]⁻-based coordination polymers, Zn(pyz)(NCMe)₂[AuBr₂(CN)₂]₂ (1; pyz = pyrazine), Co(pyz)[AuBr₂(CN)₂]₂·H₂O (2) and [M(bipy)₂(AuBr₂(CN)₂)][ⁿBu₄N][AuBr₂(CN)₂]₂ (bipy = 4,4′-bipyridine), where M = Co (5) and Zn (6), were synthesized and three of them structurally characterized. 1 forms 1-D chains connected by pyz ligands while isostructural 5 and 6 form 3-D frameworks via [AuBr₂(CN)₂]⁻ and bipy linkers.
