 Title    Synthese und Kristallstruktur von Ba(H S04)2(H2S 0 4)3 und Sr(H S04)2(H2S 0 4) Synthesis and Structure o f B a (H S 0 4)2(H 2S 0 4)3 and S r(H S 0 4)2(H 2S 0 4)  
 Abstract    From the binary systems M 2S 0 4/H 2S 0 4 (M = Ba. Sr), two new hydrogen sulfates, (Ba(HS0 4)2(H 2S0 4)3 and S r(H S 04)2(H 2S 0 4), have been synthesized and structurally char­ acterized. Ba(HS0 4)2(H2S0 4)3 crystallizes in the orthorhombic space group P 2 12 12 , with unit cell parameters a = 4.680(1), b = 11.267(2), c = 29.188(6)A, Z = 4. B a 0 9 trigonal prismatic polyhedra with Ba-O distances of 2.68 -3.02 A from nine different S 0 4 tetrahedra are connected via common bases and build "isolated" columns consisting of O-S-O bridged double chains along the .r-axis. H S 0 4 and H2S 0 4 tetrahedra are linked via hydrogen bonds to form columns. S r(H S 04)i(H TS04) crystallizes in the triclinic space group P i with unit cell parameters a = 5.971(1), b = 8.468(2), c = 10.226(2)A, a = 81.71(3), ß = 83.30(3), 7 = 70.69(3)°, Z = 2. Sr is coordinated by nine oxygen atoms from seven different S 0 4 tetrahedra with S r-0 distances of 2.47 -2.84 A. The S r0 9 polyhedra build layers consisting of O-S-O bridged chains. Three crystallographically different S 0 4 tetrahedra are linked via hydrogen bonds to form a kind of flattened cylinder along the .v-axis.

 Abstract    p(C O)2M nN (Bz)C H 2CH2 , der erste einzähnig koordinierte A ziridin-K om plex C p(C O)2M nN (B z)C H 2C H 2, the First M ono-C oordinate A ziridine Com plex The photolytically induced CO-substitution reaction of CpM n(CO b with N-benzyl-aziridine leads to the first mono coordinate aziridine complex, Cp(CO)2MnN(Bz)CH2CH2. It is stable against thermal C2H4 elimination up to 135°C. No nitrene complexes {Cp(CO)2Mn}"NBz (/? = 1, 2) were detected. The X-ray structure analysis of Cp(CO)2MnN(Bz)CH2CH2 shows the intact three-membered ring ligand and the pyramidal configuration of the nitrogen atom.

The X-ray crystal structure of both complexes was determined: In the La(III) complex (space group P i) all donor atoms (N40 6) are coordinated. The coordination number 10 is realized in a bicapped square antiprism (SAPRS-10). The bond length La to O of the protonated carboxylic group is ca. 0.3 A longer than the other five"La-O distances. The Dy(III) complex (space group P i) exhibits coordination number 9 in a monocapped square antiprism (SAPRS-9). The protonated carboxylic group is not coordinated.

 Title    Die Verbindung MgCl2 2 ASCI3 5THF: ein Tetrachloroarsenat(III) oder ein AsC^-Solvat des MgCl2 4THF? The Compound MgCl2 2AsC13 5THF: A Tetrachloroarsenate(III) or an AsC13 Solvate of M gCl2 4THF?  
 Abstract    Magnesium Dichloride-tetrakis(tetrahydrofuran)-bis(arsenic trichloride)tetrahydrofuran. X-Ray A compound MgX2-2AsXy5THF (X = Cl.Br) has first been obtained by chance during an attempt to prepare mesitylarsenic dichloride from AsCI:, and mesitylmagnesium bromide. Then, MgCl2-2AsCly5THF was synthesized from the components. X-ray crystallography revealed that this compound is best described as [/ra/Kv-MgCl2-(THF)4)]-(2AsClyTHF). The AsC13 units are weakly interacting with the Cl atoms of the MgCl2(THF)4 molecules, while the fifth THF molecule interacts with both AsC13 units making the As atoms hexacoordinated. This arrangement generates a chain structure in the orthorhombic lattic.

 Abstract    Chlorine Nitrate The reaction of C10N 02 with PC13 yields POCl3 and NO:+N O r . With AsC13 chlorine nitrate forms a compound of the analytical composition "AsCl2(N 0 3h ", in contrast to SbCl3, which does not react with C10N 02. The reaction of C10N 02 with AsCl4+AsF6_ was reported to yield A s(0 N 0 2)4+AsF6~. We found no reaction below 273 K. Reaction at 293 K yields N 0 2+AsF6~ as solid product. SbCl5 does react, but the reaction yields no reproduceable products.
