 Title    Synthese, Eigenschaften und Kristallstruktur von (NH 4 )NbOBr 4 Synthesis, Properties and Crystal Structure of (NH 4 )NbOBr 4  
 Abstract    (NH 4)NbOBr 4 is obtained as air sensitive, light red crystals from NH 4 Br and NbBr 5 in a sealed glass ampoule at 420 °C, whereby the oxygen presumably originates from the glass surface. The compound crystallizes in the monoclinic space group C2/m with a — 1269.9(1), b = 1384.7(2). c = 773.0(2) pm, ß = 114.44(2)° and Z = 6. The structure is built up by NH 4 + cations and polymeric NbOBr 4 anions. Symmetrical linear oxo bridges with Nb-O = 199 pm connect square planar NbBr 4 units to form endless chains arranged in planes parallel (010). Neighbouring NbBr 4 units are in eclipsed as well as staggered orientations. The NH 4 + cations are located between the planes of parallel NbOBr 4 " chains. The vibrational frequencies of the IR and Raman spectrum are assigned.

 Title    Synthese und Kristallstrukturen der spirocyclischen Polyselenido-Komplexe [Na-15-Krone-5] 2 [M(Se 4 ) 2 ] mit M = Zink, Cadmium und Quecksilber Sythesis and Crystal Structures of the Spirocyclic Polyselenido Complexes [Na-15-Crown-5] 2 [M(Se 4 ) 2 ] with M = Zink, Cadmium, and Mercury  
 Abstract    The title compounds have been prepared by reactions of the metal acetates of zink, cadmium, and mercury with ethanolic solutions of sodium polyselenides in the presence of 15-crown-5. They form dark red crystals, which were characterized by their IR specta as well as by X-ray crystal structure determinations. All complexes [Na-15-crown-5] 2 [M(Se 4) 2 ] with M = Zn (1), Cd (2), Hg (3) crystallize isotypically in the space group C2/c with 4 formula units per unit cell. In the anions [M(Se 4) 2 ] 2 ^ the metal atoms are coordinated tetrahedrally by four selenium atoms of two Se 4 2 ~ units, thus forming a spiro-bicyclus. The complex cations [Na-15-crown-5] + have a Na---Se contact of approximately 299 pm with two selenium atoms of a MSe 4 group, allowing formulation of triple ion species.

 Title    [l,4,2]Diazaphospholidine [l,4,2]Diazaphospholidines  
 Abstract    Bis(diethylamino)phosphanylacetylen reacts with N.N'-dimethyl thiourea to give 2-diethyl-amino-l,4-dimethyl-3-methylene-[l,4,2]diazaphospholidine-5-thion (2) besides the [1.3.4]thi-azaphospholidine (1). The latter compound is converted into 2 by heating. Reaction of 2 with various reagents yields other members of the title compound class. All new compounds are characterized by some reactions and their NMR and IR spectra. In addition, the results of an X-ray structure analysis of 2-diethylamino-l ,4-dimethyl-3-methylene-2-thioxo-[l ,4.2]diazaphos-pholidine-5-thion (5) are reported.

 Title    Rhodium-zentrierte Bildung eines Cyclobutenyl-Liganden und Umlagerung in einen Cyclopentadienyl-Komplex Rhodium-centered Formation of a Cyclobutenyl Ligand and Rearrangement to a Cyclopentadienyl Complex  
 Abstract    Cyclization of two diphenylacetylene molecules occurs if [(cod)RhCl] 2 (cod = 1.5-cyclooc-tadiene) is treated with methyllithium in the presence of tolane. The isolated (cod)Rh complex 2 contains an e*o-methyl-tetraphenylcyclobutenyl ligand and was characterized by X-ray diffraction analysis. Thermolysis of 2 in acetonitrile causes ring expansion of the methylcyclobutenyl unit with formation of the tretraphenylcyclopentadienyl complex 3 together with 3-methyl-tet-raphenylcyclobutene. Mechanistic aspects are discussed as well as spectroscopic data of the new compounds.

 Title    Substituierte Heptaarsane(3)  
 Abstract    As 7 (Mme 3)3 (M = Si, Ge, Sn) mit Nortricyclenstruktur Substituted Heptaarsanes(3) As 7 (Mme 3) 3 (M = Si, Ge, Sn) with Nortricyelene Structure The heptaarsanes(3) As 7 (Mme 3) 3 (M = Si, Ge, Sn) with nortricyclene structure have been synthesized by heterogeneous and homogeneous reactions from K 3 As 7 and Rb 3 As 7 , respectively, with Mme 3 Cl. The crystal structures have been determined. The compounds are isotypic and crystallize in unit cells of R3 symmetry, containing pairs of enantiomers. The bond lengths d(As—As) in the nortricyclene skeleton are nearly uneffected by the substituents and show the sequence typical for covalent nortricyclenes: d(basal) = 244.3 pm > d(basal-equatorial) = 242.7 pm > d(equatorial-apical) = 240.7 pm (mean values). The spread-off of the Mme, sub-stituents decreases as going from P 7 to As 7 skeletons as well as with increasing size of M.

Dimorphie Lead(II) l,l-Dicyanoethylene-2,2-dithiolate: Preparation and Crystal Structures  
 Abstract    By reaction of Pb(CH,COO) 2 -3 H 2 0 with Na 2 S 2 C=C(CN) 2 -3 H 2 0 in water, a-PbS 2 C=C(CN) 2 is obtained. Hydrothermal conditions give small crystals of the a-and /3-phase. The crystal structures of the two phases have been determined. The a-phase is monoclinic with space group P2Jn and a = 11.879(5), b = 12.027(5), c = 4.655(1) Ä, ß = 96.94(3)°, Z = 4. The compound contains PbS 2 C 4 N 2 molecules with Pb—S = 2.66 and 2.90 Ä. Two molecules are connected to dimers with Pb-Pb = 4.44 Ä. The /3-phase also crystallizes monoclinically, space group C2/c, a = 9.613(1), b = 13.579(1), c -16.052(2) Ä, ß = 98.36°, and Z = 12. There are two independent lead positions, with the metals integrated in PbS 2 C = C(CN) 2 groups with a stereochemically active lone-pair, and dimers Pb 2 (S 2 C 4 N 2) 2 with Pb-Pb distance = 3.80 Ä.
