AbstractThe crystal chemistry of viridines and kanonaite, (AlThe structure refinements reveal that the transition metal ions substitute for Al almost exclusively in the distorted octahedral Al(l) site of the andalusite structure type within the entire mixed crystal series. This is independently proven by the Mössbauer results for

The crystal structure of [ Mn ( terpy )2](I3)2( terpy = 2,2°:6°,2°-terpyridene) has been determined by X-ray crystallography. The crystals are triclinic, space group Pī , a 9.357(4), b 8.600(2), c 24.531(8) Ǻ, α 93.64(2), B 95.58(3), γ 91.52(2)°, Z 2, V 1960(1)Ǻ3. The structure has been refined to a residual R of 0.065 (Rw 0.070). The coordination sphere of the metal ion is distorted octahedral with each terpy ligand coordinated in a meridional fashion. The structure is compared with those of other M( terpy )2n+ complexes formed by first-row transition metal ions.

N,N-diethyl-Nʹ-ferrocenoyl-thiourea and N-(morpholino-thiocarbonyl)ferrocenecarboxylic amide have been prepared by the reaction of ferrocenoyl chloride with potassium thiocyanate and the respective amine in dry acetone. These bidentate ligands yield neutral heterometalIic complexes with Ni(II), Cu(II), Mn(II) and Co(III). The dark brown air stable crystals of bis-(N,N-diethyl-Nʹ-ferrocenoylthioureato)nickel(II) were characterized by X-ray structure de­termination. Lattice dimensions: a = 1870.9(1), 6= 1161.5(1), c = 1491.4(1) pm; space group Pca21, Z = 4, R = 0.030 for 5707 observed reflections.

Similar synthetic schemes yield two different metallacrown (MC) complexes: bis(μ-3-chlorobenzoato)hexakis(dimethylformamide)tetrakis(μ4-N,2-dioxidobenzene-1-carboximidato)tetramanganese(III)disodium(I), [Mn4Na2(C7H4ClO2)2(C7H4NO3)4(C3H7NO)6] or Na2(3-chlorobenzoate)2[12-MCMn(III)N(shi)-4](DMF)6, 1, and tetra-μ-aqua-tris(μ-3-chlorobenzoato)(dimethylformamide)tetrakis(μ4-N,2-dioxidobenzene-1-carboximidato)pentamanganese(III)sodium(I) dimethylformamide tetrasolvate 0.72-hydrate, [Mn5Na(C7H4ClO2)3(C7H4NO3)4(C3H7NO)(H2O)4]·4C3H7NO·0.718H2O or MnNa(3-chlorobenzoate)3[12-MCMn(III)N(shi)-4](DMF)(H2O)4·4DMF·0.72H2O, 2, where shi3− is salicylhydroximate and DMF is N,N-dimethylformamide. Both complexes have the same framework consisting of four MnIII ions in the MC ring and four shi3− ligands, resulting in an overall square-shaped molecule. The MnIII ions are either five- or six-coordinate with elongated bond lengths in the apical or axial direction, respectively. The structure of 1 is nearly planar, and the MC binds two Na+ ions on opposite faces of the MC central cavity. The 3-chlorobenzoate anions also bind on opposite faces of the MC and form bridges between the central Na+ ions and the ring MnIII ions. For 1 the metallacrown molecule, except for the central Na+ ion, exhibits whole molecule disorder over two sets of sites. Both moieties are centrosymmetric and are related to each other by a pseudo-mirror operation with opposite sense of rotation around the Na...Na axis. The occupancy ratio of the main disorder of the metallacrown molecules and 3-chlorobenzoate anions refined to 0.9276 (9):0.0724 (9). The structure of 2 is slightly domed, and the MC binds both an MnII ion and an Na+ ion in the MC central cavity. The MnII ion is located on the convex side of the MC, while the Na+ ion binds to the concave side. Complex 2 represents the first instance of a [12-MCMn(III)N(shi)-4] molecule binding both 3d transition metal and alkali metal ions in the central cavity. In addition, three 3-chlorobenzoate anions bind on the convex side of the MC and connect the MnII ion to three of the ring MnIII ions.
