Summary
Urea (ur), thiourea (tu) and diisopropylthiourea (diptu) form high-spin complexes with iron(II), for which57Fe Mössbauer quadrupole splitting and spectroscopic data suggest an octahedral distorted geometry. The x-ray diffraction study on Fe(tu)4Cl2 confirms this geometry. The crystals are tetragonal, space groupP42/n witha=13.71,c=8.94 Å andZ=4. The molecules are centrosymmetric with two axial chlorine atoms (Fe-Cl=2.46 Å) and four equatorial sulfur atoms (Fe-S=2.61 and 2.57 Å respectively). A similartrans-octahedral geometry is proposed for the new Fe(diptu)4Cl2 complex and an octahedral metal coordination in the new [Fe(ur)6]Br2, Fe(tu)3Br2 and Fe(ur)3Br2 complexes.
