title: {Tris[2-(imidazol-2-ylmethyl-imino)eth-yl]methyl-ammonium}iron(II) tris-(per-chlorate) dihydrate.
abstract: The title complex, [Fe(C(19)H(27)N(10))](ClO(4))(3)·2H(2)O, is a new polymorph of an iron(II) Schiff base complex of tris-(2-amino-ethyl)methyl-ammonium with imidazole-2-carboxaldehyde. The octa-hedral Fe(II) atom is bound to three facial imidazole N atoms with average Fe-N(imidazole) and Fe-N(imine) bond distances of 1.963 (5) and 1.951 (5) Å, respectively. The central N atom of the tripodal ligand is outside the bonding distance at 3.92 Å. The crystal packing is stabilized by the hydrogen-bonding inter-actions between the two water mol-ecules (acceptor) and two of the three imidazole NH groups (donor). The third imidazole NH group (donor) forms a hydrogen bond to one of the three perchlorate counter-ions (acceptor).
