SUMMARY

The coordination compounds [CU(CN)3]2- and [Ni(H2O)6]2+ are correctly identified as tricyanocuprate (I) and hexaaquanickel (II), respectively. The term "aquo" is the accurate descriptor for the water ligands in hexaaquanickel (II), as opposed to "aqua." This discussion confirms the nomenclature used in coordination chemistry for these specific compounds.

PREREQUISITES
  • Understanding of coordination chemistry terminology
  • Familiarity with ligand types and their nomenclature
  • Knowledge of oxidation states in transition metal complexes
  • Basic principles of chemical bonding in coordination compounds
NEXT STEPS
  • Research the properties and applications of tricyanocuprate (I)
  • Explore the role of hexaaquanickel (II) in biological systems
  • Study the differences between "aqua" and "aquo" in coordination chemistry
  • Investigate the synthesis methods for coordination compounds
USEFUL FOR

Chemistry students, educators, and researchers focusing on coordination chemistry and transition metal complexes.

1) [CU(CN)3]2- =tricyanocuprate (I)


2) [Ni(H2O)6]2+ =hexaaquanickel (II)


is that right?

Correct.


2) [Ni(H2O)6]2+ =hexaaquanickel (II)

It's "aquo", not "aqua", but otherwise, it's okay.
 
I would have said hexaaquanickel too... but maybe that's just my exam board?! :smile:
