 Title    Darstellung eines cyclischen Ferrocenderivates mit Wolfram (VI) Preparation of a Cyclic Ferrocene Derivative of Tungsten(VI)  
 Abstract    Ph2PC 5 H4FeC 5 H4PPh2 (1) reacts with Me3SiN3 with evolution of nitrogen to yield (Me3SiN = PPh2C 5 H4)2Fe (2). Treatment of 2 with WF6 results in the formation of (C 5 H4PPh2N)2FeWF4 (3). 3 is a rare example of a metal complex containing two metal atoms in very different oxidation states.

 Title    (CuI)2Pi4* ein neues Phosphorpolymer in einer Kupferhalogenid-Matrix (CuI)2P 14: a Novel Phosphorus Polymer in a Copper Halide Matrix  
 Abstract    (CuI)2Pi4 is a new adduct of copper iodide to a neutral phosphorus polymer. It is obtained by reaction of Cul and Pred at 400 °C. The compound crystallizes monoclinically, space group P2,/c (No. 14), a = 9.919(2), b = 9.718(2), c = 16.478(3) Ä, ß = 105.71(1)°, V = 1529.0(7) A3, with Z = 4. The crystal structure was refined to R\ = 0.029 for 2680 reflections and 173 parameters. It contains a new polymeric phosphorus allotrope with the translational unit P^° consisting of experimentally unknown [PI2] groups which are linked by [P2] fragments. The phosphorus rods consist of five-and six-membered rings, and are coordinated only by copper atoms.

 Title    Synthese und Struktur eines Strontium -V anadyl-Phosphats: Sr2( V 0 ) (P 0 4)2 Synthesis and Structure o f a Strontium Vanadyl Phosphate: Sr2(V 0 )(P 0 4)2  
 Abstract    Dark green single crystals of Sr2(VO)P2Ox have been prepared by solid state reactions in closed quartz tubes. X-ray investigations led to monoclinic symmetry, space group C2h-I2/c/, a = 6.744(4), b = 15.866(4), c = 7.032(2) Ä, ß = 115.41(2), Z = 4. Sr2(VO)P2O s is isotypic to Sr2(VO)V2Os and shows V4+ in split positions. The split positions are in non-centric octahedral coordination forming a short vanadium to oxygen distance typical for the vanadyl group. The crystal chemistry of the monovanadyl orthophate Sr2(VO)P2O x is discussed considering related divanadyl phosphates.

 Title    K[B6PO10(OH)4]: Ein Borophosphat mit gestreckten Bändern aus Tetraeder-Vierer-Ringen und offen-zyklischen Verzweigungen über planare B203(0 H)2-Gruppen K[B6PO 10(OH)4]: A Borophosphate Containing Rods of Tetrahedral Vierer-Rings with Additional Open-Loop Branchings via Planar B20 3(0 H )2 Groups  
 Abstract    K[B6PO|0(OH)4] was prepared under mild hydrothermal conditions (T = 170 °C) from a concentrated solution of K2B40 7 ■ 4H20 , KH2P 04, and HC1 (18%). The crystal structure of the tetragonal compound was solved by X-ray single crystal methods (space group P 4/ncc, No 130): a = 1209.66(13), c = 759.05(7) pm; Z = 4. The anionic partial structure consists of infinite rods of ^ [B6POl0(OH)4]~ which are built of vierer-rings of alternating B 0 4 and P04 tetrahedra with additional open-loop branchings via planar B20 3(0 H)2 groups at the B 0 4 units by sharing common oxygen functions. Potassium (K+) is located within structural channels running along [001]; the eightfold coordination by oxygen (OH-groups) results in a (slightly) distorted tetragonal antiprism.

 Abstract    [P(NH2)4]Br and [P(NH2)41[N 03] have been prepared by anion exchange in liquid ammonia. Single crystals of [P(NH2)4]Br were obtained from an acetonitrile solution in a tempera­ ture gradient between 60 °C and room temperature while attempts to grow single crystals of [P(NH2)4][N 0 3] yielded [P(NH2)4][N 0 3](O P(N H 2)3). Both crystal structures were determined by single crystal X-ray methods at room temperature ([P(NH-))4]Br: P4/nbm, a = 809.2(1), c = 468.1(1) pm, Z = 2, R \ = 0.042, wR2 = 0.077; [P(NH2)4][NÖ3](OP(NH2)3): Pna2,, Z = 4, a = 1023.4(1), b = 1704.7(1), c = 618.0(1) pm, R \ =0.025', wR2 = 0.067. In the solid [P(NH2)4]Br forms a tetragonally distorted variant of the CsCl type of structure. [P(NH2)4][N 0 3](0P (N H 2)3) consists of [P(NH2)4]+cations, [N 0 3]_ anions, and OP(NH2)3 molecules which are interconnec­ ted by a complex system of hydrogen bonds.

 Title    Photoelektronenspektren von Verbindungen der V. Hauptgruppe, III 1 Methylhalogenverbindungen MeEHal2 und Me2EHal Photoelectron Spectra of Group V Compounds, III 1 Methylhalogen Compounds MeEHal2 and Me2EHal  
 Abstract    The He I photoelectron spectra of certain MeEHal2 and MeaEHal compounds (E = (N), P, As, Sb; Hal = (F), Cl, Br, J; Me = CH3) are interpreted in terms of a "composite molecule" approach derived for C3v/Cs systems. Although an "internal standard" is missing here, substituent group-orbitals (njjai, C-H) may be classified with respect to their orien-tations in space (R, V, T). Ionisation energies are assigned according to this assumption. PE data of the isoelectronic EMe3/EHal3 compounds and of related molecules (Me2EH, MePH2, CF3PBr2) as well as EHMO calculations with partial inclusion of spin orbit coupling are used to confirm the assignments given for Me2EHal/MeEHal2 series. Correlations between PE ionisation energies (e.g. nE (IE)) and molecular or atomic properties are critically revised and discussed.

The data provide evidence by which sample purity and crystallinity may be exam ined and from which the size o f the asymmetric unit may be determ ined. In the case o f the sodium salts o f ethane-1.2-diphosphonic acid, the 3IP and _3Na spectra provide evidence o f possible motion or bond fluctionality for the phosphonic acid group.

 Title    Synthese und Struktur des ersten dreigliedrigen Arsen—Phosphor—Platin-Ringes Synthesis and Structure of the First Three-Membered Ring Containing Arsenic, Phosphorus and Platinum  
 Abstract    -butylphenylphosphane reacts with CpFe(C,H4AsCl2) in the presence of DBU to yield CpFe[C5H4As=PC6H2(f-Bu)?l. The reaction of this arsaphosphene with (Ph3P)2PtC2H4 yields CpFe[C5H4As—P[C6H2(r-Bu)3]Pt(PPh3)2], a compound with a three-membered ring containing arsenic, phosphorus and platinum.

 Abstract    , Struktur und Reaktivität des Pentaphosphids (/Bu3Si)3P5Na2 und des Pentaphosphans (fBu3Si)3P5 [2] Supersilyl Compounds of Phosphorus, V [1]. Preparation, Structure, and Reactivity of the Pentaphosphide (?Bu3Si)3P5Na2 and the Pentaphosphane (?Bu3Si)3P5 [2] The orange THF adduct (fBu3Si)3 P5Na2(THF)4 of the pentaphosphide (rBu3Si)3P5Na2 (3) has been prepared, (i) by protolysis of the tetraphosphide (?Bu3Si)2P4Na2(THFj;! (2) with CF3C 0 2H in THF (molar ratio 2 : 1) , (ii) by dissolving crystalline 2 in toluene, and (iii) by the reaction of P4 with /Bu3 SiNa(THF)2 in benzene (molar ratio 1 : 4). According to an X-ray structural analysis, the THF adduct of 3 contains a P3 ring with two PNa(Si?Bu3) substituents in cis position and one SifBu3 substituent in trans position to the former groups. The protolysis of 3 with CF3C 0 2H leads to the pentaphosphane P5 H2(SifBu3) 3 (9), the silylation of 3 with Me2SiCl2 to the pentaphosphane P5(SiMe2)(Si?Bu3) 3 (10), and the oxidation of 3 with C2(CN)4 to the pentaphosphane P5 (Si/Bu3) 3 (5). The structures of 3,5,9, and 10 have been assigned from 1|P and ~4Si NMR data. The pentaphosphane 5 contains a hitherto unknown Ps backbone of a P3 ring anellated with a P4 ring.
