Crystal structure of bis{μ-2-[(dimethylamino)methyl]ferroceneselenolato}bis[chloridopalladium(II)]

The dinuclear title compound, [PdCl{Se[(C5H5)Fe(C5H3)2CH2N(CH3)2]}]2 was obtained by the reaction of [PdCl2(NCPh)2] with 2-[(N,N′-dimethylamino)methyl]ferroceneselenolate and the crystals for the structure determination were grown from a mixture of THF and n-hexane. Both PdII atoms are coordinated by the bridging Se atoms and by the amino N atoms of the bidentate 2-[(N,N′-dimethylamino)methyl]ferroceneselenolate ligand, as well as by Cl atoms, and show a distorted square-planar coordination. The angle between the Pd—Se—Se planes of the two Pd atoms is 149.31 (3)°. Weak Cl...H hydrogen bonds link the binuclear complexes into a three-dimensional network

Crystal structure of tris(phenylselenolato-κSe)tris(tetrahydrofuran-κO)thulium(III)

In the title compound, [Tm(C6H5Se)3(C4H8O)3], the TmIII atom lies on a threefold rotation axis and is coordinated by three phenylselenolate ligands and three tetrahydrofuran ligands leading to a distorted fac-octahedral coordination environment. The Tm—Se and Tm—O bond lengths are 2.7692 (17) and 2.345 (10) Å, respectively, and the bond angles are 91.32 (6)° for Se—Tm—Se, 92.6 (2) and 94.4 (2)° for Se—Tm—O, and 81.2 (3)° for O—Tm—O. In the crystal, the discrete complexes are linked by van der Waals interactions only. The crystal was refined as a non-merohedral twin (ratio = 0.65:0.35)
