	Title	Synthese und Reaktivität von 7-Triphenylstannyl-a-am inobuttersäure- derivaten
	Abstract	Ph3SnCH2CH 2C H (NHCOOCH 2P h)COOCH3 (1) is synthesized by hydrostannation of methyl N-(benzyloxycarbonyl)vinylglycinate with Ph3SnH. The reaction o f 1 with HC1 in CH 3OH and with bromine in CHC13 yields the halostannylsubstituted compounds Ph3_"X,?SnCH2CH 2C H(NHCOOCH 2Ph)C OOCH3 (2 -4) (n = 1, 2; X = Cl, Br). By sapo nification with one equivalent of NaOH and subsequent acidification with HCl 1 is transformed into the free acid Ph3SnCH2C H 2C H(NHCOOCH2Ph)COOH (5) that undergoes cyclization into the 1,2-oxastanninane 6 with intramolecular elimination of benzene. IR, NMR data and the determination of the crystal structure of Ph2BrSnCH2CH2CH(NHCOOCH2Ph)COOCH3(3) reveal for 2 and 3 an intramolecular coordination of the N C (0)0-group at the tin atom to form a seven-membered ring.

	Title	Coordination Chemistry of Lipoic Acid and Related Compounds, Part 1 Syntheses and Crystal Structures of the UV-and Light-Sensitive Lipoato Complexes [M(lip)2(H20 ) 2] (M = Zn, Cd)
	Abstract	The rac-lipoato (lip-) complexes [Zn(lip)2(H 2 0)2] (1) and [Cd(lip)2(H2 0)2] (2) were ob tained in good yields from solutions of sodium lipoate and the respective metal nitrate in methanol/water. 1 and 2 form pale yellow, moderately light-sensitive crystals. Both compounds were structurally characterized by single-crystal X-ray diffraction. 1: C2/c, a = 39.958(6), b = 5.360(1), c = 10.794(1) Ä, ß = 95.76(1)°, Z = 4, wR2 = 0.150 (all data). 2: C2/c, a = 38.200(2), b = 5.472(1), c = 11.179(1) Ä, ß = 92.72(1)°, Z = 4, wR2 = 0.090 (all data). The metal ions are hexacoordinated by the oxygen atoms of two chelating carboxylate ligands and two aqua ligands. The crystal structures are very similar but not isotypic. They are layer structures, in which the complexes within a layer are interconnected by a network of hydrogen bonds. Adjacent layers have contacts via the 1,2-dithiolanyl rings of their lipoato ligands. Crystals of 1 and 2 decompose on exposure to visible light or ultraviolet radiation in the 2 8 0 -3 9 0 nm range. Photopolymerization by formation of intermolecular S-S bonds is very probably involved. Furthermore, the infrared spectra reveal the transformation of CO O -into COOH groups.

	Title	Photochemische Synthese neuer zinnorganischer Verbindungen mit "aktiven" Gruppen am Zinnatom (I) Photochem ical Synthesis o f New Tinorganic C om pounds with Active Substituents on Tin
	Abstract	By photochemically induced oxidative addition reactions the synthesis of some new tinorganic compounds was achieved. The reaction of dichloro-and diiodotin with 1,2-diiodobenzene (1) induced by ultraviolet radiation led to bis-(1 -iodophenyl)diiodotin (2), bis-(1 -iodophenyl)dichlorotin (3), 1 -iodo-2-(trichlorotin)benzene (4) and 1 -iodo-2-(triiodotin)benzene (5). Iodosubstitution at the tin atom was also observed when dichlorotin was used as the starting compound. Analogous experiments with 1,2-dibromobenzene (6) and 1,2-dichloro-(7) gave no products.

	Title	-Allylgermatrane. Synthesis, Structure and Reaction with Diazomethane
	Abstract	Reaction of allyltribromogermane (2), readily available from dibrom o(l,4-dioxane)ger-manium(II) (1) and allylbromide, with tris(2-tributylstannoxyethyl)-amine (4) gives 1-allylgermatrane (3) in almost quantitative yield. 3 crystallizes from /7-pentane as a colourless crystalline solid which was characterized by 'H and ,3C NMR spectroscopy and by an X-ray crystal structure study. The "atrane" skeleton shows a strong conformational disorder; the Ge-N distance of 2.208(3) A suggests the presence of a coordinative Ge-N bond. Treatment of 1 -allylgermatrane (3) with CH2N2 in the presence of catalytic amounts of Pd(OAc)2 affords 1-cyclopropylmethylgermatrane (5) in high yield.

	Title	Über die Kristallstrukturen der Tellurate Pb3Fe2Te20 12 und Pb2CoTe06
	Abstract	Pb3Fe2Te20 \|2 (I) and Pb2C oT e06 (II) have been prepared by crystallization from melts. Single crystal X-ray investigations led to monoclinic (I) and tetragonal (II) symmetry, space groups Cs-Cc and D{J-I4/mmm. Lattice constants I: a = 9.866(3), b = 15.332(4), c = 7.172(2) A, ß = 111.34(3)°, Z = 4. II: a = 5.661(5), c = 8.004(7) A, Z = 2. (I) represents a new crystal structure, characterized by a network of octahedra occupied by Fe + and Te6+ in a disordered manner. The centres of negative charge of the lone pairs of Pb2+ in I are estimated by Coulomb term calculations. II belongs to the elpasolithe type.

The reaction of l,l',3,3'-tetraphenylferrocene with CH 3C (0)C1 results in the formation of Fe[C5H ,{ C (0)C H 3}{(C 6H4C (0)C H 3)2}]-[C5H 3{(C 6H4C (0)C H 3)2}] (5), whereas 2c and FeCl2 give Fe[C5H3(C6H4C(0)C5H M)2]2 (4c).

	Title	Structural Investigation of Bis(isonitrile)gold(I) Complexes
	Abstract	The reaction of (MeNC)-, (PhNC)-and (MesNC)AuCl in tetrahydrofuran with an equimolar amount of the corresponding isonitrile ligand and one equivalent of Ag+X~ (X -= BF^ or CF3S O J) leads to the formation of the bis(isonitrile)gold(I) complexes (MeNC)aAu+ CFiSO ^ (1), (PhNC)2Au+ BF^ (2) and (M esNC)2Au+ BF^ (3). The crystal structures of 1, 2 and 3 have been determined. In compound 1 there are rod-like cations with a parallel packing into meandering puckered layers, in which the gold atoms have alternating A u-A u contacts of 3.611 and 3.624 A. In complex 2 the cations form long double-paddles, with the two paddles at an angle of 11.5°. The individual cations are well separated and have no sub-van-der-Waals A u-A u contacts. The crystal structure of 3 is similar, but with a smaller dihedral angle between the planes of the two mesityl rings (56.0°).

	Title	M
	Abstract	The dication of tetrakis(dimethylamino)ethene (TDAE2+) forms ion pair complexes with [M(mnt)2]2~, mnt2-= maleonitrile-2,3-dithiolate, M(II) = Ni, Pd, Pt, and Zn. According to X-ray analysis the structure of {TDAE2+[Pt(mnt)2]2~ } consists of a chain-like arrangement o f planar dianions and twisted (71°) dications. Shortest interionic contacts are 11 pm longer than the corresponding van der Waals radii. In the UV-VIS diffuse reflectance spectra of the complexes with a d8 central metal there is no unambiguous evidence for the presence of an ion pair CT band. This band is observed, however, at 450 nm when the d 10 metal Zn(II) is present. Application of the Hush-Marcus model affords a reorganization energy of 110 kJ / mol for electron transfer from [Zn(mnt)2]2-to TDAE2+. This value is 40 kJ / mol higher than the one reported for the analogous complex wherein TDAE2+ is replaced by a 2,2'-bipyridinium acceptor of similar reduction potential.

	Abstract	The applicability of ketals was examined for masking the carbonyl group in N-tertiary 4-piperidones during the dehydrogenation using mercury-edta. Various 1,3-dioxolanes showed a different behaviour in dependence on the N-substituent. With simple aliphatic moieties mainly dehydrogenated but hydrolyzed products were received. These enaminones were also available from the dehydrogenations of the corresponding 4-piperidones. Similar applied to para-acyl-aromatic substituted derivatives but with less yields. Aromatic substituents bearing a neighbour group on ortho-position with participation gave rise to different oxidation products partially with preservation of the ketal structure.

	Title	Die Synthese und Kristallstruktur des Borat-Phosphats: a -Zn3(B0 3)(P04) Synthesis and Crystal Structure of the Borate-Phosphate: Q-Zn3(B 0 3)( P 0 4)
	Abstract	Single crystals of the compound a -Z n 3(B 0 3)(P 0 4) were obtained at 1050 °C by using B20 3, P20 5 and Z n C 0 3 as starting materials and subsequent cooling to 600°C with 20°C/h. X-ray investigations on single crystals yield a new crystal structure in the monoclinic space group Cm -(Nr. 8) with a = 972.5(2); b = 1272.0(3); c = 487.4(3) pm; 0 = 1 1 9 .8 0 (4)°; Z = 4. The structure contains isolated trigonally planar B 0 3 and tetrahedral P 0 4 units which are not joined together. Zinc occupies three crystallographically different point positions and is trigonal-bipyramidally, tetragonal-pyramidally or distorted tetrahedrally coordinated by oxygen.

	Title	Occurrence of Toxin Producing Cyanobacteria in Hungary. Isolation, Separation and Identification of Microcystins
	Abstract	Cyanobacteria (blue-green algae), Microcystis aeruginosa sp., were isolated from a massive bloom in a eutrophic waterbody in Hungary. Their toxic effect, determined by a mouse test, was associated with the occurrence of microcystins YR and LR which were isolated, separated by means of HPLC procedures and identified by mass spectroscopy. The toxin content of the dry cell material is about 0.22 %, indicating a pronounced toxin-producing ability of the species investigated.
