John Stride from the University of New South Wales, Sydney and colleagues have prepared a copper-based metal–organic framework that demonstrates gas selective adsorption of hydrogen over nitrogen.

The microporous framework has potential application in the isolation of hydrogen from nitrogen in ammonia sythesis waste streams.

In this Dalton Transactions Hot Article, chemists from Australia and the US have studied the solution behaviour of two novel platinum-based antitumour complexes.

The dinuclear, polyamine-linked complexes show significant cytotoxicity and antitumour activity compared to other polynuclear platinum complexes.

The rate constants for hydrolysis of the two complexes and the acid dissociation constants of the aquated aqua ligands of their aquated derivatives are reported. The values are of interest because the aquated species are more reactive than their hydroxo counterparts in the context of DNA binding.
