The N -substituted glycine derivatives obtained are interesting candidates for peptide modification.

 Title    Binuclear Fulvalene and Bis(cyclopentadienyl)methane Halfsandwich Complexes of Manganese and Rhenium Containing Tetrahydrothiophene Ligands. X-Ray Structure Analysis of {(CO )2MnIC5H4-C 5H4lMn(CO)2}(/i-SC4H 8)  
 Abstract    Tetrahydrothiophene Complexes, Fulvalene and Bis(cyclopentadienyl)methane Com pounds, Photosubstitution o f Carbonyl Ligands The photo-induced substitution o f carbonyl ligands in the binuclear cyclopentadienyl-type complexes (CO)3M [C5H4(C H 2)"C5H 4]M (CO)3 (n = 0 (fulvalene), M = Mn (1) and Re (2); n = 1 (bis(cyclopentadienyl)methane), M = Mn (3) and Re (4)) has been studied in the presence o f tetrahydrothiophene, SC4H8 (tht). Photodecarbonylation o f 1 -4 in tetrahydrofuran solution leads to solvent-stabilized intermediates which react with tht in the dark to give m onosubsti­ tuted derivatives (C O)3M [C5H 4(C H 2)nC5H 4]M (CO)2(tht) (la ~ 4 a). In the case o f M = M n, tht-bridged com pounds {(C O)2M n[C5H4(C H 2)nC5H4]M n(CO)2}(J w-tht) (n = 0 (lb) and n = 1 (3b)) are also obtained which are the exclusive products o f the photolysis o f 1 and 3 in benzene in the presence o f tht. Photodecarbonylation o f 1 -4 in neat tetrahydrothiophene produces disubsti­ tuted derivatives in the case o f manganese, (tht)(CO)2Mn[C5H4(C H 2)nC5H 4]M n(CO)2(tht) (n = 0 (lc) and n = 1 (3c)), whereas only the monosubstituted complexes 2a and 4 a could be isolat­ ed in the case o f rhenium. The molecular structure o f the tht-bridged fulvalene complex lb has been determined by an X-ray structure analysis. A special reaction o f dimethyl disulfane with the photolyzed tetrahydrofuran solution o f 2 leads to the bis(methylthiolato) com pound (C O)3Re[C5H4-C 5H4]R e(CO)(SM e)2 (5). The new complexes were characterized by their IR spectra v(CO) and their 'H and 13C N M R spectra.

 Title    On the Hydrolysis of Monoorganotin Trihalides, V**. Solid State 119Sn-NM R and IR Spectra of the [(/-PrSn)120 14( 0 H ) 6|2+ Ion  
 Abstract    M onoorganotin Oxygen Compounds, 119Sn-CPM A S-N M R Spectra, IR Spectra The 1 l9Sn-CPM AS-NM R spectra of the complex [(/-PrSn)pO |4(OH6)]2+ ion were recorded for two different salts having twelve and four different tin atoms in the asymmetric unit, re­ spectively. Both spectra agree very well with X-ray crystallographic predictions, and thus dem­ onstrate the great sensitivity of heavy nuclei N M R spectroscopy to subtle structural changes. Infrared spectroscopy is shown to be a suitable routine detection method for the identification of this ion in the solid state.

The X-ray structures of the com pounds 2 -Pyridin, 3 and 8 show Cl-bridged dimers in the solid state, while 6 and 7*0.5 MeCN are monomeric. In the diphenylsulfiminates 2-Pyridin and 3 short T e -N bond distances are found.

The com pound crystallizes tetragonally, space group I4,/a, with a = 5,8401(5), c = 13,265(2) A at 297(1) K, and a = 5,8289(7), c = 13,109(2) A at 159(3) K, respectively. Except for a significant decrease in the anisotropic displace­ ment factors, the changes in the structural para­ meters at low temperature are rather small.

 Title    On the Space Group of Cesium Perbromate, CsBrÖ4  
 Abstract    The correct space group of cesium perbromate, C sB r04, is 14,/amd and not 14,/a as previously reported. The com pound is isostructural with a-C sR e 0 4, the high-temperature modification of cesium perrhenate. By analogy with C sR e04 and C s I0 4, a phase transform ation to a low-tempera-ture modification is predicted for C sB r04.

 Title    Ein Orthoperrhenat mit flächenverknüpften R e 0 6-0ktaedern: Hochdrucksynthese und Kristallstruktur von K3NaRe20 9 An Orthoperrhenate with Face-Sharing R e 0 6 Octahedra: High-Pressure Synthesis and Crystal Structure of K 3N aR e20 9  
 Abstract    The title com pound was prepared by high-pres­ sure reaction of rhenium metal with technical grade (i.e., N a containing) K O , in a modified Belt-type apparatus (20 kbar, 1Ö00 °C, 60 min, Au capsule). The amber-coloured crystals are very hygroscopic and decompose rapidly when exposed to air. K 3N aR e20 9 crystallizes hexago-nally, space group P 63/mmc, with a = 6.012(1), c = 14.342(14)Ä, c/a = 2.386 and Z = 2. The structure was refined to R = 0.031, R w = 0.023 for 422 independent, absorption-corrected reflections with l> a (I). K 3N aR e20 9 is isostructural with 6 H -B a T i0 3, a perowskite variant, and contains Na and Re in octaedral coordination. Two R e 0 6 octahedra are face-sharing, thus creating a Re20 9 double octahedron with a R e -R e distance of 2.92Ä.

 Abstract    bM gSn und Eu3M g4Sn4, erste ternäre Verbindungen in den D reistoffsystem en Seltene E r d e n -M a g n e siu m -Z in n YbMgSn and Eu3Mg4Sn4, First Ternary Compounds in the Systems Rare E a r th s -M agnesium -T in H. Allescher-Last Two new ternary com pounds YbMgSn and Eu?Mg4Sn4 have been prepared and characterized by X-ray diffraction. YbMgSn crystallizes in the Fe-,P-type structure, space group P-62m. The com pound Eu3Mg4Sn4 crystallizes orthorhom bi-cally in the space group Immm. It is isotypic to Li4Sr3Sb4. The structures were calculated from single crystal data.
