Area of Science:

• Organometallic Chemistry
• Inorganic Chemistry
• Materials Science

Background:

• Iron-bismuth halide chemistry is an emerging field with potential applications.
• Synthesis of novel compounds with unique structural motifs is crucial for advancing materials science.

Purpose of the Study:

• To synthesize and characterize novel pentamethylcyclopentadienyl substituted iron-bismuth halide compounds.
• To explore new synthetic routes for iron-bismuth halide complexes and coordination polymers.

Main Methods:

• Synthesis of iron-bismuth halides [Bi{FeCp*(CO)2}X2] from [FeCp*(CO)2]2 and BiX3.
• Isolation and characterization of a novel coordination polymer [FeCp*(CO)2(CH3CN)]2n[Bi4Cl14]n.
• Preparation of a novel ionic complex [{FeCp*(CO)2Br]2[Bi6Br22{FeCp*(CO)2}]·CH2Cl2 by altering molar ratios.

Main Results:

• Successfully synthesized three iron-bismuth halide compounds: [Bi{FeCp*(CO)2}X2] (X = Cl, Br, I).
• Isolated a novel coordination polymer and a novel ionic complex through controlled reactions.
• Demonstrated a more convenient synthetic route using [FeCp*(CO)2X] with BiCl3 and BiBr3.

Conclusions:

• The study expands the library of known iron-bismuth halide compounds.
• The developed synthetic methods offer improved accessibility to complex iron-bismuth materials.
• These findings contribute to the understanding of structure-property relationships in organometallic halide compounds.
