Gezielte Synthese von Sulfinato-O- und -S-Komplexen einiger Übergangsmetalle. XII. Uber ein- und zweikernige Sulfinato-S-Komplexe von Palladium(II)

Directed Synthesis of Sulfinato-O and -S Complexes of Some Transition Metals. XII Mono- and binuclear Sulfinato-S Complexes of Palladium(II) According to equations (1–7) the preparation of new mono- and binuclear sulfinato complexes of palladium(II) of the type Na[PdCl(S(O)₂R)₂(OH₂)], (RS(O)₂)₂PdL_n (R = C₆H₅, p-CH₃C₆H₄; n = 2: L = H₂O, py, PPh₃; n = 1: L = bpy, phen, en) and [AsPh₄]₂[(RS(O)₂)_2+n Pd₂Cl_4—n] (n = 0, 2) is reported. While the pyridine compounds are trans-configurated, all the other mononuclear complexes have cis-configuration. In the binuclear complexes the bridging ligands are chlorine, [AsPh₄]₂[PhS(O)₂)₂Pd₂Cl₄]on the basis of the IR spectra has a center of symmetry. The anionic tetra(organosulfinato-S)palladate(II) complexes [AsPh₄]₂[Pd(S(O)₂R)₄] could be obtained for the first time by reaction of [AsPh₄]₂[PdCl₄] with silver sulfinates according to equation (10). In all compounds, the IR and electronic spectra of which are discussed in detail, the RSO₂^? ligand is coordinated to palladium via sulphur.

Synthese und Molekülstrukturen von amido‐ und imidoverbrückten Clustern elektronenreicher Übergangsmetalle

Synthesis and Structures of Amido‐ and Imidobridged Clusters of Electron‐rich Transition Metals We report in this article the results, which could be obtained within the DFG‐Project “Nitridobrücken zwischen Übergangsmetallen und Hauptgruppenelementen”. Reactions of electron‐rich transition metal compounds with either stannylated or lithiated amine derivatives lead in the presence of phosphines in different organic solvents to the formation of a large amount of nitrogenbridged transition metal clusters. The structures of 1 — 27 have been characterized by single crystal X‐ray‐structure analysis.     

Dichlorophosphate zweiwertiger Übergangsmetalle von Mangan,Eisen, Kobalt,Nickel und Kupfer

Dichlorophosphates of the Divalent Transition Metals Manganese, Iron, Cobalt, Nickel, and Copper The dichlorophosphates M(O₂PCl₂)₂ · 2 POCl₃ with M = Mn, Fe, Ni and Co(O₂PCl₂)₂ are prepared from the metal acetates and POCl₃, whereas Cu(O₂PCl₂)₂ only yields from the formiate and P₂O₃Cl₄. The finely distributed metals Fe, Co, and Ni react with excess dichlorophosphoric acid. forming the complexes M(O₂PCl₂)₂ · 2 HOPOCl₂. According to the vibrational spectra, the metal atoms are linked to polymeric 8-ring structures by O? P? O bridges. Moreover the dichlorophosphoric acid solvates are stabilized by hydrogen bridges.     

Über Chalkogenidfluoride einiger Seltener Erden

The compounds LaSF, CeSF, EuSF and LaSeF were prepared by reaction of the sesquichalcogenides with the fluorides. The sulphidefluorides crystallize with the PbFCl structure, while LaSeF crystallizes with an unknown orthorhombic structure.
