Abstract:Polyiodides of acetamide complexes of transition elements have been synthesized and studied by X-ray diffraction analysis. Compounds M(AA)6]I10] (M = Mn, Fe, Co, Ni, Zn) are isostructural with the earlier studied cadmium compound. The crystals of Co(AA)4(H2O)2]I12] are monoclinic: a = 17.486(6) Å, b = 15.015(4) Å, c = 7.8309(15) Å, β = 99.87(2)°, V = 2025.6(10) Å3, space group C2/m, Z = 4. The crystals of Ni(AA)6]I3]2 are monoclinic: a = 23.032(9) Å, b = 12.176(4) Å, c = 18.274(5) Å, β = 139.22(3)°, V = 3347.0(19) Å3, space group Cc, Z = 4.
