 Title    Oxidative Knüpfung einer Phosphor-Phosphor-Bindung unter Einwirkung von Ag(I)-bzw. Cu(II)-Ionen: Synthese und Struktur von [(C 6 H5)PH 2 Ag{|i-(C 6 H 5 PH) 2 }]2 (AsF 6 ) 2 , einem sechsgliedrigen Silber-Phosphor-Ring The Oxidative Formation of a Phosphorus-Phosphorus Bond in the Presence of Ag(I) and Cu(II) Ions: Synthesis and Structure of [(C 6 H 5 )PH 2 Ag{^-(C 6 H 5 PH) 2 }] 2 (AsF 6 ) 2 , Containing a Six-Membered Silver-Phosphorus Ring  
 Abstract    The reaction between AgAsF 6 and phenylphosphine proceeds with formation of a phosphorus-phosphorus bond. The main product 1, [(C 6 H 5)PH 2 Ag{u-(C 6 H 5 PH) 2 }] 2 (AsF 6) 2 , was characterized by an X-ray structure determination [PI, a = 919.0(4), b = 1109.8(4), c = 1316.4(5) pm, a = 97.48(3), ß = 107.25(3), y = 102.71(3)°, Z = 1, R = 0.057 for 2806 observed reflections], 1 contains Ag 2 P 4 rings; the silver atoms are further coordinated by phenylphosphine ligands, thus acquiring trigonal coordination geometry. A similar reaction is observed with Cu(AsF 6) 2 , forming the analogous Cu(I) complex 2.

 Title    Ag+ als Substituent eines Alkalimetalls in Ag2SrMnV20 8  
 Abstract    Single crystals of Ag2 SrM nV20 8 have been prepared by reactions of metallic silver and a mixture of S rC 0 3, M nC 03 HoO and V ?0 5. X-Ray investigations showed monoclinic symmetry, space group Cfh-C2/c, a = 9.7022(9), b = 5.5882(5), c = 13.894(1), ß = 90.41(1)°, Z = 4. The crystal structure is isotypic to N a2BaCuV20 8 and includes V 0 4 tetrahedra, M n 0 6 octahedra as well as irregular A g 0 8 and S rO !0 polyhedra. Ag2SrM nV20 8 is characterized by a [MnV20 8] network incorporating Ag+ and S r + or a [Ag2V 2Ö 8] frame incorporating Mn2+ and Sr2+ ions. Ag+ is able to replace an alkali ion in the cationic part of the crystal structure.

 Title    Uber das Oxomolybdat AgKCu3Mo4Oi6 mit Silber in siebenfacher Koordination About the Oxomolybdate AgKCu3Mo4O i6 with Silver in Seven-Fold Coordination  
 Abstract    Single crystals of AgKCu3Mo40 16 have been prepared by crystallization from melts and investigated by X-ray diffractometer techniques. This compound crystallizes with monoclinic symmetry, space group C |h-P 2 Je, a = 5.056(1), b = 14.546(4), c = 19.858(9) Ä, ß = 86.64(5)°, Z = 4. The crystal structure of AgKCu3Mo40 16 is closely related to K2Cu3Mo40 16 showing ribbons of edge-sharing C u 0 6 and AgÖ7 polyhedra. The ribbons are linked by tetrahedrally coordinated molybdenum and K2O 10 groups. Another kind of M o 0 4 tetrahedra occupies the cavities inside the ribbons. The crystal structure and the coordination of silver, copper, potas­ sium and molybdenum by oxygen are discussed with respect to K2Cu3Mo40 16.

 Abstract    Single crystals of A g 04Na23Ca43RuO8 have been prepared by heating Na20 2, CaO and ruthenium in closed silver tubes. Silver took part in the reaction. The crystal structure was investigated by X-ray techniques. A g 04N a2.3Ca43R uO 8 crystallizes with orthorhombic sym­ metry, space group D^-Cm m m ; a = 9.255(1), b = 6.683(1), c = 6.696(3) Ä , Z = 2. It shows relations to the sodium chloride structure. A statistical distribution of A g + and N a+ can be separated in micro space by splitting one oxygen position to give a dumb-bell like O -A g -O and an octahedral N a 0 6 coordination.

 Abstract    Single crystals of AgSr[B70 , 2] were obtained by using a B20 3 flux-technique and Ag2C 0 3 and SrC 03 as starting materials in a silver ampoule at 800 °C. X-ray investigations on single crystals led to the space group C 2/c with a = 664.2(5); b = 1153.6(3); c = 2198.0(6) pm; ß = 92,52(3)°; Z = 8. Ag+ is fourfold coordinated by oxygen atoms and forms distorted A g04 tetrahedra while Sr2+ has nine nearest neighbours. The compound contains a hitherto unknown two dimensional borate anion [B70 i 2]3-which contains four trigonal planar B 0 3 groups and three B 0 4 tetrahedra per unit.

 Abstract    Single crystals o f Ag2C s[B ,50 24] were prepared by using a B 20 3 flux technique with Ag2C 0 3 and Cs2C 0 3 in a closed silver tube at 650 °C. X-Ray investigations led to a new crystal structure in the space group P 2 ,2 ,2 (Nr. 18) with lattice parameters a = 1778.7 (4); b = 2219.2 (4); c = 512.2 (1) pm, Z = 4. The silver atoms are part of distorted A g 0 4 tetrahedra and planar A g 0 3 units while the caesium atoms are eightfold coordinated by oxygen. The compound contains an as yet unknown borate anion [B,50 24] with twelve B 0 3-and three B 0 4 units per formula. The B 0 3 units are connected to eight cords twisted to helices which are combined via B 0 4 tetrahedra to a three dimensional framework with large tunnels occupied by the cations.

 Title    Antimony as a Donor Atom in Silver Coordination Chemistry: Synthesis, IR Spectra and Structure of the Silver(I) Cyanoximate Complexes with Triphenylstibine and Triphenylphosphine Model Compounds  
 Abstract    Silver(I) cyanoximate complexes Ag{ONC(CN)-R} (R = COPh, {L1}; COC(CH3)3, {L2}; benzothiazol-2-yl, {L3}) with triphenylphosphine and -stibine of compositions Ag(PPh3)n{L} (n = 2, 4) and Ag(SbPh3)n{L} (n = 3 for {L1} and {L2}, n = 2 for {L3}) were synthesized by the reaction of the components in acetonitrile solution and characterized by elemental analyses and IR spectroscopy. The crystal structures of Ag(SbPh3)3{L} (L = {L } (1), { L2} (2), Ag(SbPh3)2{L3} CH3CN (3) and Ag(PPh3)2{L '}C H 3CN (4), have been determined by X-ray diffraction. For all the compounds examined the coordination environment of the silver atom has the geometry of a distorted terahedron ([AgP2NO] (4); [AgSb3N] (1), (2); [AgSb2N2] (3)). The bis adducts Ag(EPh3)«{L} adopt molecular structures, in which the organic anions are coordinated in bidentate chelate fashion via the nitroso nitrogen atom and the oxygen (nitrogen for { L3}) atom of the substituent R. In the fm-stibino complexes (Ag-Sb 2.670(4) -2.7748(8) A; Sb-Ag-Sb 108.87(4) -115.00(2)°) the cyanoximates are unidentate ligands and coordinated via the nitroso nitrogen atoms (Ag-N ca. 2.35(1) A). The different behaviour of N ,0 and N,N chelating cyanoximes under the same conditions suggests, that the Sb donor triphenylstibine is able to substitute the oxygen atoms in the silver(I) coordination sphere, but not the nitrogen ones. This causes the formation of 1:3 adducts of Ag{L} with SbPh3 for N ,0 donors {L 1} and {L2}, and only 1:2 for N,N donor anionic {L3}.

 Title    Quaternary Selenidogermanates(IV) A3[AgGe4Se10]*2H2O and A2[MnGe4Se10]*3H2O (A = Rb, Cs) with Open Framework Structures  
 Abstract    Hydrothermal reaction of Ge and Se with Ag(CH3COO) in the presence of alkali metal carbonates affords the open framework selenidogermanates(IV) A^fAgGejSeiol ^H^O (A = Rb, Cs), 1 and 2, which contain corner linked adamantane-like Ge4Seio cages and AgSe4 tetrahedra. The analogous reaction with Mn(CHiCOO)2 yields the isostructural tetragonal compounds A2[MnGe4Seio]-3 H2 0 (A = Rb, Cs), 3 and 4. The cations are sited at a general position in the channels of the silver bridged anionic framework of 1 and 2 and exhibit a disordered pattern of occupation (s.o.f. = 0.75) with one of the two crystallographically independent water oxygen atoms 0 (2) (s.o.f. = 0.25). In contrast, the Rb+ cations in 3 are disordered over all three cation/oxygen sites, and the cation/water occupation pattern is fully reversed for the larger Cs+ cations in 4 in comparison to 1 and 2.
