 Title    Eine neue Synthese von Fluorphosphonat-Komplexen des Palladiums und Platins A New Synthesis of Fluorophosphonato Complexes of Palladium and Platinum  
 Abstract    Addition of phosphorus(III) ligands, L (L = tertiary phosphine, phosphite) to the reaction mixture of allyldifluorophosphite (1) with (C 6 H5CN)2MCl2 (2) (M = Pd, Pt) was found to produce two types of products: after a shorter reaction period, monofluoro-phosphonate complexes of the previously known type £rans-L2MCl(POF2) (6) are obtained while over prolonged periods of time bis-fluorophosphonato complexes, Zrans-L2M(POF2)2 (7) are formed. By contrast, Bu"OPF2 (8) yields a mixture of «rans-L2PtCl(POF2) (6) and <rons-L2PtCl[(Bu"0)(F)P0] (10) (L = Ph3P), the latter originating from (Bu re O)2PF formed by ligand scrambling in Bu*OPF2; no products containing more than one fluorophos-phonate group are formed in this case. The new monofluorophosphite, (CH2 = CHCH20)2PF (10) was found to react rapidly with (C6H5CN)2PtCl2/L with formation of L2PtCl[(CH2==CHCH20)(F)P0] (11). Compound characterization was by IR, 19 F and 31 P NMR spectroscopy.

 Abstract    A series of mono and bis N,O-chelate complexes 1-32 with the mono and dianion of indigo and indigo derivatives (R3P)(C1)M(L-H+) (M = Pd.Pt), (r/3-allyl)Pd(L-H+), (PhiC=NCH->CO->Et-H+)Pd(L-H+), (PhN=NPh-H+)Pd(L-H+), (Q H 5)Fe(C5H3CH2NMe2)Pd(L-H+), [(R3P)(Cl)Pt]2(L-2H+), [(//3-allyl)Pd]2(L-2H+), [(C6H4CH2N M e2)Pd]2(L-2H+) with L = indigo, 4,4'-dichloro-, 6,6'-dichloro-, 6,6'-dibromo-, 6,6'-di-»Bu-, 4,4'-dichloro-, 5.5'dibromo-, 5,5', 6,6'-tetramethoxy-, 4.4'-di-S]2H25-, 5,5'-di-SO?Na-indigo, indigo malonic ester and tetrahydro indigo have been prepared from chloro bridged metal complexes. In comparison to the free neutral indigo ligands the complexes show a high bathochromic shift in the VIS spectra (150-300 nm) which is mainly due to the anionic character of the coordinated indigo ligands. The structure of [(Et3P)(Cl)Pt]2(indigo-2H+) has been determined by X-ray diffraction. Metallkomplexe von Farbstoffen, VIII [1]

 Title    Metal Complexes of Biologically Important Ligands, CXXV [1]. Palladium(II) and Platinum(II) Complexes of Quinine Derivatives and in vitro Tests  
 Abstract    Several quinine substituted derivatives at the C(9)-0 position (1 -7) have been obtained from quinine and N-protected glycine chloride, chlorocarbonyl ferrocene, phenylisocyanate, dicarboxylic acid dichlorides or trimesinic trichloride. From these only the glycine derivative 1 showed significant antimalarial activity in in vitro tests against Plasmodium falciparum

 Title    Pt(NH3)2(SCN)2J: Ein Platinkomplex mit gemischter Wertigkeit Pt(NH3)2(SCN)2I: A Mixed Valence Platinum Compound  
 Abstract    Pt(NH3)2(SCN)2 dissolved in liquid SO2 reacts with molecular iodine to yield a green lustrous solid of stoichiometry Pt(NH3)2(SCN)2I. The compound is diamagnetic in the solid state and in solution and has to be taken for a platinum(II, IV) mixed valence compound, therefore. Chemical and physical evidence so far suggest a linear chain solid with either iodide-bridged metal complex chains or metal complex stacks with parallel triiodide chains.

 Title    A New Synthesis of Organodifluorophosphites and their Reactions with Platinum(II) Complexes  
 Abstract    Alkyldifluorophosphites, ROPF2 (R = ^-substituted benzyl group, neopentyl, 1-ada-mantyl) have been obtained by a new method, involving reaction of the appropriate alkyl trimethylsilylether, ROSiMe3 with chlorodifluorophosphine, PF2C1. Reactions of these difluorophosphites with platinum(II) complexes of the type [LaPtCla] (L = PEt3, PPI13) led to products such as irans-[L2PtCl(POF2)] and {[p-XC6H4CH2PPh3]+}2[Pt(POF2)4] 2 -, (X = H, Me, Cl, N02). The ease of carbon-oxygen cleavage in ROPF2 is characteristically related to the nature of the leaving group, R.

 Abstract    The isotypic compounds SrPt 4 P 6 , SrPt 4 As 6 and BaPt 4 As 6 were found to crystallize with a Pyrite-type derivative structure (monoclinic, C2/c, Z = 4) in which one Sr or Ba atom per formula unit occupies the position of a P 2 or As 2 pair. BaPt 2 P 3 forms another Pyrite-type related structure (monoclinic, I > 2 1 /c, Z = 4) built up by Ba 2 Pt and Pt 3 P 6 layers. All crystal structures were refined from four-circle diffractometer data, the lattice constants are:

 Abstract    Single crystals of the phase NaBa4Cu0 5P t1 s0 8 were prepared in closed silver tubes. The black and moisture sensitive crystals were investigated by four-circle diffractometer X-ray tech­ niques. They show trigonal symmetry, space group D2-P321, a = 10.0644, c = 8.3811 A, Z = 3 and belong to the perovskites. The typical M20 9 double octahedra are occupied by Pt4+ and Cu2+ in a different manner. Na+ is partly in and out of the centres of trigonal prisms of oxygen. These features will be discussed with respect

 Abstract    Reactions of B a C 0 3, ZnO and Yb20 3 mixtures at temperatures up to 1300 °C using plati­ num crucibles led to yellow needles of B a17Y b 16Zn8Pt40 57. The compound crystallizes with a hitherto unknown tetragonal crystal structure, space group C-4h-I4/m, a = 22.731(1), c = 5.682(1) A , Z = 2. The crystal structure is characterized by P t 0 6 octahedra and tetragonal Z n 0 5 pyramids. Yb3+ shows a mono-capped trigonal prismatic coordination and Ba2+ several different coordination environments (C .N = 9 to 10, by O2"). The relationship to the Ba5Ln8M40 2i type is discussed.

 Abstract    Reactions of mixtures of B aC 03, ZnO, Sm20 3 (3:5: 1) heated in platinum crucibles up to 1250 °C led to big black single crystals of Ba4Sm4Zn3P t0 15. The new compound crystallizes with hexagonal symmetry, space group C^-Pö^mc, a = 1 L657, c = 6,789 A , Z = 2. It is isotypic with Ba6Nd2Al4O l5 but shows an ordered Pt4+ and Zn2+ distribution over the aluminium positions. The octahedrally coordinated barium sites of the Ba6Nd2Al40 15 type are occupied by Sm3+. In comparison to compounds of the composition Ba6Ln2M40 15 (M = Al, Fe, Co), Ba4Sm4Zn3PtOi5 is the first example containing different oxidation states at the M '+ positions.

 Abstract    Single crystals of Bai3Dy8Zn4Pt40 37 have been prepared by reaction of mixtures of BaC03, ZnO and Dy20 3 at temperatures up to 1225 °C using platinum crucibles. X-ray investigations led to a new crystal structure with tetragonal symmetry, space group C4h-I4/m, a = 18.659(7), c = 5.734(2) A, Z = 2. The structure is characterized by P t0 6 and B a06 octahedra as well as by tetragonal Z n 0 5 pyramids and single capped trigonal prisms of oxygen around dysprosium. The remaining barium positions show coordination numbers of nine and ten. The crystal structure has large ^ [(PtDy40)6)4] polyhedra tunnels. Considering the 1 [Ln4O l6]20_ polyhedra groups some parts of the structure show similarities to BaZnLn20 5, B a ^ n 4Ln8Ö2i and Ba2Ln2ZnPt08.

 Title    Metal Complexes of Heteroarenes, X [1]. 7 7 1 -Coordination of Phosphinine: Synthesis and Structure of cis-Dichloro-bis(2,6-dimethyl-4-phenyI-phosphinine)platinum  
 Abstract    C/5-Dichloro-bis(2 ,6 -dimethyl-4 -phenyl-77'-phosphinine)platinum (3) has been prepared by ligand substitution from cis -dichloro(2,5-cyclooctadiene)platinum and characterized by spec­ troscopy ('H , 13C, 31P NMR, IR, UV-Vis), CV and X-ray diffraction (space group P2|/c, a = 14.998, b = 16.540, c -11.506 Ä, a = 7 = 90°, ß = 92.46°, Z = 4). In line with findings for simi­ lar P hybridization states, the Pt-P bond length (221 pm) in 3 equals that in 771 -phosphaalkene Pt complexes and falls short of the respective parameters in Pt phosphane species. The stretching frequencies u^c\ and the bond length Pt-Cl indicate that phosphinines and phosphaalkenes, relative to phosphanes, adopt a lower position on the rram'-influence scale. This gradation is also suggested by the coupling constants 1 J (195Pt,31P).
