An indenide-tethered N-heterocyclic stannylene

Area of Science:

• Organometallic Chemistry
• Crystallography
• Coordination Chemistry

Background:

• Organotin compounds exhibit diverse coordination behaviors.
• Understanding ligand interactions is crucial for designing novel materials.

Purpose of the Study:

• To elucidate the crystal structure of a novel lithium-tin complex.
• To investigate the coordination modes of tin within this complex.

Main Methods:

• Single-crystal X-ray diffraction at 100 K.
• Database survey of tin, germanium, and lead coordination modes.

Main Results:

• The lithium-tin compound crystallizes in monoclinic (P21/n) symmetry.
• Tin exhibits an unusual η2 coordination to the indenyl ring.
• Tin displays a broader range of coordination modes compared to germanium and lead.

Conclusions:

• The study provides detailed structural insights into a unique organotin complex.
• The findings expand the understanding of tin's coordination chemistry with indenyl ligands.
