Synthesis, characterization and electrochemical properties of phosphine-disubstituted diiron bis(monoselenolate) carbonyls

Heterocyclic pyrazole‐containing diiron dithiolato analogues: Synthesis, characterization, electrochemistry, and fungicidal activity

“…The phosphine ligands in analogues 3 – 6 all occupy apically to the distorted octahedron of the neighboring iron atom, analogous to other monosubstituted compounds. [ 40–42 ] The Fe 2 bond length in complex 2 [2.493(4) Å] matches well with complex [Fe 2 (CO) 6 {μ‐SCH 2 CHCH 2 O 2 C(4‐C 2 N 2 SCH 3 )S}] [2.492(3) Å]. [ 23 ] The Fe 2 bond lengths in complexes 3 – 6 are marginally longer than complex 2 due to the influence of phosphine ligand but much shorter than those of disubstituted analogues.…”
