Platinum Group

Since 1998 demand for the platinum group metals (PGM) has exceeded supply resulting in large price increases. Undersupply, combined with rising costs prompts environmentally friendly recycling technologies. Leachates containing PGM were produced from secondary waste sources using microwave leaching technology with the aim of recovering precious metals using bacterial biomass. Previous studies showed that metallised biomass exhibits catalytic activity; hence metal is not only recovered but can be converted into a valuable product. Cells of Escherichia coli MC4100 that had been pre-metallised with Pt were more effective at reducing PGM from the leachates. The solid recovered from the leachate onto the bacteria was characterised using X-ray Powder Diffraction (XRD) and Energy Dispersive X-ray Microanalysis (EDX). Metallised biomass was tested for catalytic activity (reduction of Cr(VI) to Cr(III)) to compare the ‘quality’ of polymetallic bacterial-based catalysts versus counterparts made from single and mixed metal model solutions.

Platinum Group

A singlecrystal X-ray structure determination of (2,2′-bipyridine)dichloropalladium(II), iso- morphous with the 'yellow' form of the platinum(II) analogue, has been carried out. Crystals are orthorhombic, Pbca, a 18.144(5), b 15.952(5), c 7.494(2) A, Z 8, 1113 diffractometer reflections being refined by full matrix least squares to a residual of 0.052. The planar molecules of PdCl2(bpy) are stacked into columns along the c direction, at a separation of c/2, neighbouring molecules in the stacks being related by glide planes with Pd…Pd separations of 4.587(2) A.

A single-crystal X-ray structure determination of the reagent (butane-1,4-diyl)(N,N,N′,N′- tetramethylethylenediamine)palladium(II) has shown that crystals are orthorhombic, Pbca, a 15.832(3), b 14.128(9), c 11.451(3) Ǻ, Z 8. The square planar complex has puckered PdCH2CH2CH2CH2 and PdNMe2CH2CH2NMe2 rings in which the outer carbon atoms deviate by c. �0.35 Ǻ from the 'PdC2N2' mean plane.
