 Title     
 Abstract    Chromium and tungsten carbonyls react with 3,3,4,4-tetramethyl-l,2-diazetine (1) or its mono-N-oxide (2) to form complexes (l)M(CO)5, (l)2M(CO)4, (l)M2(CO)io, (l)2M2(CO)8, (l)3M2(CO)6 or (2)M(CO)5 and (2)2M(CO)4, resp. In the reactions of 2 some deoxygenation affords complexes of 1 as by-products. The stability of these and other complexes of the N=N group is related to the ring size of the cyclic diazene ligand.

 Title    Positionsselektivität und Regiochemie bei Abfangreaktionen mit Heterokumulenen Cycloaddition Behaviour of Bis(trifluoromethyl) Substituted Nitrile Ylides [1] Site Selectivity and Regiochemistry of Trapping Reactions with Heterocumulenes  
 Abstract    3,3-bis(trifluoromethyl)-2,2-dihydro-l,4,2-oxazaphosphol-4-enes on thermolysis undergo a 1,3-dipolar cycloreversion reaction with formation of bis(trifluoro-methyl) substituted nitrile ylides and trimethyl phosphate. The nitrile ylides are trapped by N-8ulfinyl aniline, phenyl isocyanate, phenyl isothiocyanate, diphenyl ketene, and carbon disulfide. Site selectivity and regiochemistry of the [3 + 2]cycloaddition reactions are described. The results are compared with those obtained from [3 + 2]cycloaddition reactions of nitrile imines, nitrile oxides, alkyl, and aryl substituted nitrile ylides with heterocumulenes.

 Abstract    The compounds 2-7 were isolated from solutions of phenanthrene (1) and nitrogendi-oxide in carbon tetrachloride after irradiation with UV light having long wavelengths (A > 290 nm). With the help of spectroscopical methods the proposed structures are derived. Radical mechanisms are proposed for these reactions.

The molecule forms a twisted Si-P4-Si-chain with two kinds of P-P-bonds. The atoms neighbouring the silicium atoms take part in bonds of length d(P-P) = 218.8 pm, whereas the central bond d(P-P) = 221.4 pm is much longer. A special feature of the structure is a short contact d(P-P) = 345.6 pm. Therefore, the inner region of the molecule has the shape of a nearly planar trapezium of the four phosphorus atoms. The periphery of the molecule is as expected. The average bond lengths are d(P-Si) = 228.5 pm, H(P-C) — 190.2 pm, d(Si-C) = 186.6 pm, d(C-C) = 151.8 pm and d(C-H) = 94 pm.

 Abstract    New nonstoichiometric cesium bromo aurates(I,III) Csi+a;(AuBr4)(AuBr2, Br3,Br)z have been synthesized, in which the almost equally shaped anions AuBro -and Br3~ can inter-change themselves. The compounds crystallize in a disordered cubic perovskite structure with a = 547.5 pm or in a tetragonal superstructure with a 16-fold perovskite cell (a = 1553, c = 1099 pm). The investigations show that other bromoaurates as the previously reported "Cs2AgAuBr6" can contain perceptible amounts of Br3 _ ions also. The IR and 197 Au Mössbauer spectra of the new bromoaurates and of Cs2AuoBr6 are discussed.

 Title    On the Crystal Structure of HgZn3  
 Abstract    The crystal structure of the intermetallic phase HgZn3 was determined using X-ray single crystal and powder diffraction methods. The phase belongs to the orthorhombic system, most probable space group being Cmc2i, and appears to be isostructural with /S'-Cu3Ti. Under standard preparative conditions a statistical distribution of both atomic species was observed.

 Title    Phosphinsubstituierte Chelatliganden, IV [1] Neue Diphenylphosphinoformamid-Komplexe des Mangans und Eisens Phosphine Substituted Chelate Ligands, IV [1] New Diphenylphosphino Formamide Complexes of Manganese and Iron  
 Abstract    The phosphino and (thio)phosphoryl formamides la, b, 2a-c, 3a, b, 4a, b which were partially unknown are synthesized by various methods, and their reactions with carbonyl-metal halides of manganese and iron are described. The formation of the P,N-and S,N-coordinate chelate complexes, (CO)4MnL (5 a, 8a), is limited to the N-phenyl derivatives la and 4a. With L = 2a, b, the unidentate P-coordination predominates. Thus, the carbonylmetal halide complexes cis-(CO)4Mn(X)L (6a, b: X = CI, 7a, b: X = Br) and 7? 5 -C5H5(CO)Fe(X)L (9a, b: X = I, 10a, b: X = Br) are obtained. Due to the low stability of the formamide complexes, their formation is always accompanied by isocyanate elimi-nation as a side-reaction.
