Area of Science:

  • Organometallic Chemistry
  • Coordination Chemistry
  • Materials Science

Background:

  • Titanium nitride clusters are challenging to synthesize and functionalize.
  • The incorporation of transition metals into titanium nitride frameworks is of significant interest for novel catalytic and electronic properties.

Purpose of the Study:

  • To synthesize novel ionic and neutral azaheterometallocubane complexes by reacting a titanium nitride cluster with rhodium and iridium precursors.
  • To characterize the structure and electronic properties of these new complexes using X-ray crystallography and computational methods.

Main Methods:

  • Synthesis of titanium nitride cluster (1).
  • Reaction of cluster (1) with rhodium and iridium diolefin complexes to form ionic complexes (2-5).
  • Anion metathesis to form tetrafluoroborate salts (4, 5).
