AbstractWFG (I) setzt sich mit dem Silylamin (II) bei Raumtemperatur je nach den Mengenverhältnissen der Reaktionspartner zu den Verbindungen (III) (monomer) oder (IV) (polymer) um und reagiert analog mit dem Siloxan (V) zu dem monomeren Aroxypentafluorid (VI).
Thionyl tetrafluoride reacts with arylsilyl ethers to give substituted derivatives ArO·S(:O)F3(Ar = Ph; o-, m-, p-MeC6H4; m-, p-ClC6H4; o-, m-, p-FC6H4), (ArO)2S(:O)F2(Ar = Ph, p-MeC6H4, p-ClC6H4, p-NO2·C6H4), (ArO)3S(:O)F (Ar = Ph, p-MeC6H4, p-ClC6H4, C6F5), (m-MeC6H4O)4SO, and (o-C6H4O2)2SO. Spectroscopic data and modes of thermal and hydrolytic decomposition were studied for most derivatives. The thionyl trifluorides and difluorides appear to have structures based on a trigonal bipyramidal co-ordination about sulphur.

AbstractDie unter Wasser‐ und Sauerstoffausschluß in Äther durchgeführte Titelreaktion führt ‐ ist das Amin (II) der Reaktionspartner ‐ abhängig vom stöchiometrischen Verhältnis zu den Mono‐ und Diamido‐Nb‐ und ‐Ta‐fluoriden (III).
The following new transition metal pentafluoride complexes with organic ligands have been prepared: MF5L (M = Nb or Ta, L =; Me2SO, EtCN, or CH2ClCN) (nc), TaF5(2-Me-py) (nc), MoF5L (L = MeCN or CH2ClCN) (nc) and TaF5(4-Me-py)2 (nc). Their vibrational spectra and those of MF5NCMe (M = Nb or Ta) and MF5L2 (M = Nb or Ta, L = Me2SO or py) are discussed in terms of the previously proposed structures, monomeric MF5L and [MF4L4+] [MF6−].
Bis(trifluoromethyl) disulphide under photolysis with some organometallic compounds in low oxidation states gives trifluoromethylthio-derivatives. On reaction with further ligands the trifluoromethylthio-group remains co-ordinated. The new compounds (cp)Mo(CO)3SCF3, (cp)W(CO)3SCF3, [Fe(CO)3SCF3]2, [Fe2(CO)6SCF3]2S, [(cp)NiSCF3]2, [(cp)Mo(CO)2SCF3]2, [Fe(CO)2PPh3SCF3]2, and (cp)NiPPh3SCF3 are reported.
AbstractDie W‐fluoride (II) reagieren mit dem Si‐Derivat (I) zu den Amidowolframfluoriden (III) und Trimethylsiliciumfluorid.
The crystal structure of trans-diaquobis(pyridine-2-carboxamide)copper(II) chloride has been determined from three-dimensional X-ray photographic data. The crystals are monoclinic, space group P21/c with Z= 2 in a unit cell of dimensions a= 6·32, b= 10·34, c= 14·69 Å and β= 114·9°. The structure is built up of centrosymmetric complex ions and chloride ions. The ligand molecules are co-ordinated through the ring nitrogen and amide oxygen; the chelate ligand is distorted out of the co-ordination plane. The octahedron is completed by two water molecules, bonded at a distance of 2·54 Å. The i.r. spectrum is discussed with respect to the crystal structure, and confirms the existence of extensive hydrogen bonding throughout the unit cell.
