Three iron(II) complexes, [Fe(TPMA)(BIM)](ClO(4))(2)⋅0.5H(2)O (1), [Fe(TPMA)(XBIM)](ClO(4))(2) (2), and [Fe(TPMA)(XBBIM)](ClO(4))(2)⋅0.75CH(3)OH (3), were prepared by reactions of Fe(II) perchlorate and the corresponding ligands (TPMA=tris(2-pyridylmethyl)amine, BIM=2,2'-biimidazole, XBIM=1,1'-(α,α'-o-xylyl)-2,2'-biimidazole, XBBIM=1,1'-(α,α'-o-xylyl)-2,2'-bibenzimidazole).
