    Description / Table of Contents: [Fephen2X2] complexes can be prepared in a good crystalline form by splitting off 1,10-phenanthroline from the corresponding [Fephen3]X2 salts with acetone or other organic solvents, or by reaction of proper anhydrous iron(II) salts or their pyridine complexes [Fepy4X2] with two moles 1,10-phenanthroline in hot, absolute pyridine. [Fephen2X2] complexes with X = Br, Cl, SCN, SeCN, OCN, N3, HCOO, CH3COO are high-spin compounds with magnetic moments between 5.1 and 5.3 B. M. [Fepy4F2], on the other hand, reacts with 1,10-phenanthroline to give only a 1:1 complex [FephenF2]n, which probably is polymeric.
    Notes: [Fephen2X2]-Komplexe erhält man in gut kristalliner Form durch Abspaltung von 1, 10-Phenanthrolin aus entsprechenden [Fephen3]X2-Salzen mit Aceton oder anderen organischen Lösungsmitteln oder bei der Reaktion geeigneter wasserfreier Eisen(II)-Salze oder ihrer Pyridinkomplexe [Fepy4X2] mit zwei Mol 1,10-Phenanthrolin in heißem, absolutem Pyridin. Die [Fephen2X2]-Komplexe mit X = Br, Cl, SCN, SeCN, OCN, N3, HCOO, CH3COO sind high-spin-Verbindungen mit magnetischen Momenten zwischen 5,1 und 5,3 B. M. [Fepy4F2] reagiert mit 1,10-Phenanthrolin dagegen nur unter Bildung eines vermutlich polymeren 1:1-Komplexes [FephenF2]n.
