 Title    Salze der 1.2-Hydrazin-bis(dithiocarbonsäure): Darstellung, Schwingungsspektren und Struktur Preparation, V ibrational Spectra and Structure of Alkahm etal Salts of the l,2-H ydrazine-bis(dithiocarboxylic Acid)  
 Abstract    The following salts of the l,2-hydrazine-bis(dithiocarboxylic acid) have been prepared: Mi[S->CNH —NHCS^], M = N a, K and M3[S->CN-NHCS2], M — Na, K. In the solvated crystals K2 1S2C N H -N H C S 2 '] • 4 C H 3O H (a = 718.0(5), b = 1329.3(8), c = 937.7(9) pm , ß = 109.26(6)°, space group C2/m , Z = 2) the [S2C N H -N H C S 2]2" ion possesses crystallographic C2h sym metry, i.e. a trans planar structure with a N -N bond length of 139.2(3) pm. V ibrational spectra indicate a lower sym metrical anion in the unsolvated crystals. In the trianion [S2CN —N HCS2]3_ the C —N stretching vibrations are observed at 1400 and 1310 cm" 1.

 Title    Beiträge zur Untersuchung anorganischer nichtstöchiometrischer Verbindungen, XXIV3 Elektronenmikroskopische Untersuchung der Hybridphasen und Nb65Oi61F3 Contributions to the Study of Inorganic Non-Stoichiometric Com pounds, XX IV 3 Electronmicroscopical Investigation of the H ybrid Phases N b590 147F and Nb650 161F3  
 Abstract    The hybrid phases N b590 147F and N b650 16iF3 were prepared at high tem perature and investi­ gated by high resolution transmission electron microscopy. Both phases have block structures. The sample of the phase N b590 147F is very well ordered, w hereas the phase N b650 161F3 shows some defects. In a sample of Nb650 161F3 m icrodom ains of a new 2:1 hybrid phase Nb960 238F4 were found. Structural differences of the systems N b20 5/N b 0 2F and N b20 5/W 0 3 are discussed.

The com pound crystallizes in the space group P 2x/c with a = 1664.9 pm , b — 916.5 pm , c = 3089.8 pm, ß = 91.45° and Z = 8 formula units. The structure consists of two crystallographically independent but structurally nearly identical m ononuclear [(r-BuP)3C r(C O)5] complexes with the three-m em -bered ring (/-BuP)3 as an unidentate a-donor ligand. Com pared to the free molecule (r-BuP)3 the cyclophosphane ligand is slightly distorted on account of its coordination to the C r(C O)5-group.

Die Struktur von 2 und 3 als (E ,Z ,Z ,E)-1.8-B is(dior-ganylphosphino)octa-1.3.5.7-tetraen folgt aus den 31P -NM R-Spektren mit d P = 3,5 (R = /-Propyl) und dp = —12,8 (R = Phenyl) sowie aus den *H-und 13C -NM R-Spektren; die Zuordnung letzterer er­ folgte durch Messung bei 25,2 und 75,4 M Hz und durch selektive Bestrahlung der Protonen an C -l und C-3. Die beobachteten Kopplungen sind mit denen von Z-und E-D iphenylpropen-l-yl-phosphan im Einklang [5].

 Abstract    X-Ray, Methyltriphenylphosphonium-Oxotetrachloroniobate Acetonitrile The X-ray structure of PPh3Me[NbOCl4(C H 3CN)] at 210 K was solved (space group P I, two formula units per unit cell, a = 1173.5(5), b = 1130.1(4), c = 946.8(3) pm, a = 97.70(4), ß = 93.57(3), y = 78.62(3)°, 3688 inde­ pendent reflexions, R — 0.025). The material consists of cations [P(C6H5)3CH3]® and anions [NbOCl4(CH3CN)]e . The nitrogen atom of the acetonitrile solvate molecule is coordinated to the niobium centre in the fra/is-position to the oxo ligand; the NbO bond length of 169 pm corresponds to a double bond.
