	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.

	Abstract	Hexa-terf-butyldisiloxane (rBu 3 Si) 2 0 (2), hexa-rerr-butyldisilazane (d3u 3 Si) 2 NH (3), and the disiloxane (rBu 3 SiNHSuBu 2) 2 0 (4) are prepared from bis(silyl)triazene /Bu 3 SiN=N-NHSirBu 3 by reaction with water (2) and by thermolysis (3), or from silanimine rBu 2 Si=NSirBu 3 by reaction with water (4). Structures of 2—4 have been determined by X-ray crystallography (for data cf. Tables II). As a consequence of the bulkiness of the silyl groups, the heavy atom frameworks SiOSi in 2 and 4 are linear, and the SiNSi angles in 3 (167 ± 2°) and 4 (157.1°) are comparatively large.

	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.

	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.

	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 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.

	Abstract	The reaction of Li 3 P 7 (DME) 3 with crown ether 12-crown-4 and (CHT)Cr(CO) 3 yields a reddish oil, from which red crystals of [Li(12-crown-4) 2 ] 3 P 21 (THF) 2 (1), red crystals of Li 2 P 16 (12-crown-4) x (THF) 2 as well as a not yet identified yellow substance separates. From this mixture crystals of 1 could be isolated. [Li(12-crown-4),] 3 P,,(THF), (1) crystallizes in the space group P2,/a with a = 3021.1(6) pm, b = 1901.5(4) pm, c = 1603.0(4) pm, ß = 95.98(3)° and Z = 4 formula units in the unit cell. The structure is characterized by isolated ^[P 2 I 3 ~] trianions and Li(12-crown-4) 2 cations. The trianion has approximately the symmetry mm2. The bond distances d(P-P) range from 213.9 pm to 226.8 pm and are differentiated by their function in the skeleton. The bond angles /3(P-P-P) are in the range 86.1° to 107.7° and image clearly the influence of the repulsion of the non-bonded electron pairs of the strained anion. The curvature of the trianion is approx. 0.8 nm" 1 and is three times larger than the curvature evaluated from structural models.

	Title	Zur Reaktion von [Cp 2 TiCl 2 ] und [CpTiC! 3 ] mit E(SiMe 3 ) 2 (E = S, Se) Die Kristallstrukturen von [Cp 3 Ti 2 S 2 Cl], [Cp 4 Ti 2 S 2 Cl 2 ], [Cp 3 Ti 2 Se 2 CI] und [Cp4Ti 4 Se 7 0] Reaction of [Cp 2 TiCl 2 ] and [CpTiCl 3 ] with E(SiMe 3 ) 2 (E = S. Se) The Crystal Structures of [Cp 3 Ti 2 S 2 Cl], [Cp 3 Ti 2 S 2 Cl 2 ], [Cp 3 Ti 2 Se 2 Cl] and [Cp 4 Ti 4 Se 7 0]
	Abstract	The reaction of [Cp 2 TiCl 2 ] with E(SiMe 3) 2 leads to dinuclear Ti complexes. In [Cp 3 Ti 2 S 2 Cl] (1) and [Cp 3 Ti 2 Se 2 Cl] (3) two // 2 -S(Se) ligands bridge the Cp 2 Ti and CpTiCl units, respectively in contrast to these, [Cp 4 Ti 2 S 2 Cl 2 ] (2) contains a // 2 V-S 2 bridge connecting two Cp : TiCl fragments. A similar reaction of [CpTiCl 3 ] with Se(SiMe 3) 2 leads to the tetranuclear cluster [Cp 4 Ti 4 Se 7 0] (4). 4 consists of a Ti 4 -tetrahedron which encloses an oxygen atom.

	Title	[Na-15-Krone-5][MoF 2 Cl2(N 3 S2)]; Synthese und Kristallstruktur [Na-15-Crown-5][MoF 2 Cl 2 (N 3 S 2 )]; Synthesis and Crystal Structure
	Abstract	The cyclothiazeno complex [Na-15-crown-5][MoF 2 Cl 2 (N 3 S 2)] has been prepared by the reaction of sodium fluoride with [MOC1 3 (N 3 S 2)] 2 in acetonitrile solution in the presence of [15-crown-5], The compound was characterized by its IR spectrum as well as by an X-ray structure determina-tion (3560 observed independent reflexions, R = 0.039). Crystal data: monoclinic, P2,//?, Z = 4; a = 1044.8(2); b = 1513.7(2); c = 1363.8(3) pm; ß = 104.33(2)°. The structure consists of ion pairs, in which the sodium atom is seven-coordinated by the oxygen atoms of the crown ether molecule and by the two fluorine ligands of the [MOF 2 C1 2 (N 3 S 2)]~ unit. The molybdenum atom is a member of the planar MON 3 S 2 ring; the fluorine atoms are coordinated in trans position to the nitrogen atoms of the cyclothiazeno ring.
