	Title	ReCl5 * OPCl3; IR-Spektrum und Kristallstruktur ReCl5 -O PCl3; IR Spectrum and Crystal Structure
	Abstract	Single crystals of ReCl5 • OPCl3 were obtained by cooling a saturated solution of rheniumpen tachloride in phosphorylchloride. It formes black needles, which are extremely sensitive to mois ture. In the IR spectrum v(PO) is shifted downwards by 140 cm-1 in comparison with liquid POCl3, indicating coordination via oxygen. The crystal structure was solved and refined from X-ray diffraction data (space group Pnma, four formula units per unit cell, a = 1629, b = 790, c = 877 pm, 902 observed, independent reflexions, R = 0.040). The complex forms discrete molecules ReCl5 • OPC1, with symmetry Cs (m). Bond lengths are Re —O — 214 pm and P —O = 146 pm, the angle Re —O —P is 143°.

	Title	Atran-analoge Verbindungen des Typs Me(R)SiSiMe (OCH2CH2)2N I I (I) o
	Abstract	c h 2 Atrane Analogous C om pounds of the Type M e(R)SiSiM e (OCH->CH2)?N I 1 (1) Heterocyclic cage compounds of type I (compounds 8—10) have been prepared by condensa tion reactions of 1,2,2-trifunctional disilanes M e(R)XSiSiM eX2 (R = Me, Ph, OEt; X = NMe2, OEt) with triethanolamine using the "Dilution Principle". The starting compounds are obtained by Si—Me cleavage of Si2Me6 with acetylchloride/AlCl3 followed by either aminolysis with HNMe2 or alcoholysis with EtOH. 'H NMR spectra indicate N—*Si(l) intraction with the more acidic Si

M olecular Structure of (d m p e)(P 0 3)Ni(C2F[4) Synthesis and properties of tris(phosphane)(ethene)nickel(0) complexes (dmpe)(PR3)Ni(C2H 4) (R = CH3 (4), c-C6H u (5), and C6H5 (6)) are reported. In solution. 4—6 are thermolabile and undergo ligand exchange reactions affording tetrakis(phosphane)nickel(0) and bis(phosphane)-(ethene)nickel(O) complexes. 1H , 13C, and 31P NMR data of 4 —6 confirm the tetrahedral geo metry around nickel. For 6 , the crystal and molecular structure has been determined by X-ray crystallography.

	Title	Azaborolinyl-Komplexe, XV [1] Bis(f/5-l,2-azaborolinyI)ruthenium-Sandwichkomplexe — Darstellung und Strukturuntersuchung
	Abstract	The synthesis of bis(l-rer?-butyl-2 -methyl-?75-l , 2 -azaborolinyl)ruthenium (1) and bis(2-methyl-l-trimethylsilyl-^5-l , 2 -azaborolinyl)ruthenium (2) succeeds when RuCL is reacted with the cor responding 1,2-azaborolinyl lithium compounds in THF at —70 °C. Each of the sandwich complex forms two isomers with a clockwise and an anti-clockwise conformation of the azaborolinyl rings. The anti-clockwise isomer of 1 (la) gives colourless crystals which were investigated by single crystal X-ray diffraction methods. The molecular structure shows the rings in an eclipsed orienta tion forming an interplanar angle of 8 .6 °. The isomers of 1 as well as of 2 give different 'H and "B NMR signals.
