(Ether-phosphane)iron(II) Complexes with the Coordination Numbers Four, Five, and SixPhotolysis of cis,cis,trans1-Br2(OC)2 Fe(P∑O)2 (1a, b) [O,P=Ph2PCH2CH2OCH3 (a), Ph2PCH2C4H7O (b)] results in the formation of the iron(II) complexes Br2Fe(P∼O)2 (2a), [BrFe-(P∩O)(μ1-Br)]2 (4b), and [trans1-Br2Fe(P∩O)(μ1-CO)]2 (5a) with the coordination numbers four, five, and six, respectively. 2a crystallizes in the triclinic space group P\documentclass{article}\pagestyle{empty}\begin{document}$\bar{1}$\end{document} with Z=2 and has two monodentated O,P functions (P∼O: η1-P1-coordinated; P∩O:η2-O,P1-coordinated). The dimeric complex 4b with two O∩P-chelated ligands crystallizes in the orthorhombic space group Pbca with Z=4. 2a and 4b, which react under CO pressure to give the starting complexes 1a, b, are also accessible from the ether-phosphanes 3a, b and anhydrous FeBr2.
