• An unusual cobalt compound
  

  Searching for small but stable cobalt compounds, a team has discovered a complex that is relevant for material research and exhibits properties that have not been reported for almost 50 years for a compound alike. A research team from Ruhr-Universität Bochum (RUB) and Carleton University in Ottawa h more

• Cobalt-based catalysts promise to enhance heavy oil extraction
  

  Despite the large number of existing reagents, research is ongoing in the world to obtain universal catalysts that are distinguished by their efficiency, low cost and neutral impact on the environment. After conducting laboratory studies, KFU scientists were able to create a new type of reagent base more

• BASF announces Schwarzheide, Germany, as location for cathode active material production in Europe
  

  BASF is announcing a new battery materials production site in Schwarzheide, Germany, as part of its multi-step investment plan to support the European electric vehicle (EV) value chain. This state-of-the art plant will produce cathode active materials (CAM) with an initial capacity enabling the supp more

Colours of Transition Metal Ions in Aqueous Solution

This graphic looks at the colours of transition metal ions when they are in aqueous solution (in water), and also looks at the reason why we see coloured compounds and complexes for transition metals. This helps explain, for example, why rust (iron oxide) is an orange colour, and why the Statue of L more

Testing for Cations

A previous post looked at the colours of transition metals, and the origin of their colours – this graphic, on the other hand, looks at how transition metals (and some non-transition metals) can be identified by the precipitates they form with sodium hydroxide and ammonia solutions. I’m going to kee more

Transition Metals

This graphic looks at some general properties of the transition metals – I had a little less space to work with than with the previous graphics, on account of the large number of elements that the transition metals encompass, but hopefully what’s included is still of use. more

• Synthesis of cationic molybdenum-cobalt heterometallic clusters protected against hydrolysis by macrocyclic triazacyclononane complexes

  Four kinds of cobalt-polyoxomolybdenum clusters were synthesized by a combination of polyoxomolybdates and a Co-tacn (tacn = 1,4,7-triazacyclononane) complex. The heterometallic polynuclear clusters were obtained by the reaction of Na2MoO4 and [Co(tacn)(H2O)3](CF3SO3)3∙H2O in aqueous solution. The p more

• On the possibility of an Eley–Rideal mechanism for ammonia synthesis on Mn6N5+x (x = 1)-(111) surfaces

  Recently we reported an Eley–Rideal/Mars–van Krevelen mechanism for ammonia synthesis on cobalt molybdenum nitride (Co3Mo3N). In this mechanism hydrogenation of activated dinitrogen occurs directly from the gas phase in a low barrier step forming a hydrazinylidene intermediate [[double bond, length more

• Iron(II) and cobalt(II) complexes based on anionic phenanthroline-imidazolate ligands: reversible single-crystal-to-single-crystal transformations

  A series of low-spin FeII and CoII complexes based on phenanthroline-imidazolate (PIMP) ligands is reported. The FeII complex (H9O4)[Fe(PIMP)3]·(C4H10O)2(H2O) (1a) shows reversible crystalline phase transformations to afford two new phases (H9O4)[Fe(PIMP)3]·(H2O) (1b) and (H9O4)[Fe(PIMP)3]·(C8H18O)( more
