Emerging trends in research and development on earth abundant materials for ammonia degradation coupled with H generation.

Ammonia, as an essential and economical fuel, is a key intermediate for the production of innumerable nitrogen-based compounds. Such compounds have found vast applications in the agricultural world, biological world (amino acids, proteins, and DNA), and various other chemical transformations. However, unlike other compounds, the decomposition of ammonia is widely recognized as an important step towards a safe and sustainable environment.

Assembly of a coordination polymer with sulphate-capped pentamolybdate units and copper: synthesis, structure, magnetic and catalytic studies.

A new coordination polymer based on the sulphate-capped pentamolybdate unit has been synthesized from the reaction of {MoSBr} with copper(II) bromide and pyridine, in DMF. The as-synthesized compound, formulated as [Cu(CHN)][{MoVI5O(SO)}{Cu(CHN)(DMF)(HO)}][MoVI5O(SO)]·2DMF (1), crystallizes in the monoclinic space group of 2/. This compound has a one-dimensional double-chain coordination polymeric structure, composed of the pentameric {MoVI5O(SO)} and the {Cu(CHN)} units, and has been characterized in the solid-state with single-crystal and powder X-ray diffraction, infrared and optical spectroscopy, as well as thermal and magnetic studies.
