SUMMARY

The discussion centers on the solubility challenges of bis-(dimethylglyoxime-nickel (II)), with the chemical formula Ni[CH3C(NOH)C(NOH)CH3]2. The user has tested various solvents including water, ethanol, cyclohexane, hydrochloric acid, chloroform substitutes, and ammonia solution, all of which failed to dissolve the compound. The Merck Index indicates that bis-(dimethylglyoxime-nickel (II)) is 'appreciably soluble' in absolute alcohol, suggesting this as a potential solution. Additionally, the user inquires about the products formed when bis-(dimethylglyoxime-nickel (II)) reacts with hydrochloric acid, noting the formation of a colorless solution.

PREREQUISITES
  • Understanding of ligand field theory
  • Knowledge of transition metal chemistry
  • Familiarity with solubility principles in organic and inorganic chemistry
  • Experience with spectroscopic techniques
NEXT STEPS
  • Research the solubility of transition metal complexes in various solvents
  • Explore the chemical behavior of bis-(dimethylglyoxime-nickel (II)) in acidic environments
  • Investigate the use of absolute alcohol as a solvent for metal complexes
  • Learn about the spectroscopic analysis of paramagnetic compounds
USEFUL FOR

Chemistry students, researchers in inorganic chemistry, and professionals working with transition metal complexes will benefit from this discussion, particularly those focused on solubility and spectroscopic analysis.

yeh basically I am doing an experiment into ligand fields and paramagnetic effects, possible inter-relations etc... and i have a range of transition metals and have proceeded to make complex ions from them, however i wish to pass them through a spectrometer but clearly this can't be done if the ion in question doesn't dissolve... does anyone know of any solvent that i can use to dissolve bis-(dimethylglyoxime-nickel (II)), formula Ni[CH3C(NOH)C(NOH)CH3]2?? its really annoying me, so far i have tried water, ethanol, cyclohexane, 5mol/l hydrochloric acid, a chloroform substitute and 6mol/l ammonia solution... and none have worked, the only other option i can think of is diethyl ether but i feel that it won't work due to its organic nature...

also out of interest, anyone know what would be formed if bis-(dimethylglyoxime-nickel (II)) reacted with hydrochloric acid because a colourless solution was formed and if I am honest i don't have a clue what it was...

thanks

The Merck Index has it 'appreciably soluble' in absolute alcohol. Terrible waste of Absolut in my opinion, though...
 
hrmm yeh agreed.. thanks anyway though
