%X The following hydroxy-bridged iron(III) complexes have been isolated for the first time : [phen2 Fe(OH)2Fe phen2](SO4)2,7H2O, [phen2 Fe(OH)2Fe phen2]Br4,2H2O, [bipy2 Fe(OH)2Fe bipy2](SO4)2,9H2O. Attempts to prepare thiocyanate derivatives of these complexes resulted unexpectedly in the synthesis of the compounds Fe(SCN)2 phen2,H2O and [FeSCN phen2]ClO4 which were investigated in the light of the well-known complexes of the type FeX2 chelate2. The compound [Fe phen3][Fe(CN)4 phen],5H2O which, except for water, has the same stoicheiometry as Fe(CN)4 phen2, is also described for the first time.   The claim by Madeja (Chemicke Zvesti, 1965, 19, 186) that the compound Fe(SCN)2 bipy2 exists both as a red trans form (&#956;eff 3.0 B.M.) and a violet cis form (&#956;eff 5.2 B.M.) is not justified according to this work. It seems that the red form may be a mixture of the paramagnetic bis- and the diamagnetic tris-compounds.
