Abstract
Several new coordinatively unsaturated iron(II) complexes of the types [Fe(SNR-Ph)X2] (X=Cl, Br; R=H, Me, Et) and the dimeric complex [Fe(SNH–Ph)(μ-Cl)Cl]2 containing bidentate N-(2-pyridyl)amino-diphenylphosphine sulfides were prepared and characterized by various methods including X-ray crystallography, 57Fe Mössbauer spectroscopy, SQUID magnetometry, ESI-MS and DFT calculations. All complexes exhibit magnetic moments very close to 4.9μB reflecting the four unpaired d-electrons. In solution, as revealed by ESI MS studies, all compounds appear to be labile and complexes [Fe(SNR-Ph)X2] seem to be in equilibrium with solvated FeX2, free ligand, and the five-coordinate cationic complexes [Fe(SNR-Ph)2X]+. The latter are the most prominent species in the ESI mass spectra. Despite their relatively low formal electron count all iron complexes were inert towards the addition of carbon monoxide.
