 Title    Chemie polyfunktioneller Moleküle, 114 [1]  
 Abstract    Synthese und Struktur eines ionischen und nichtionischen, cyclischen Carbaphosphazens und eines Cobalt(III)phosphazen-Komplexes C hem istry of Polyfunctional M olecules, 114 [1] Synthesis and Structure of an Ionic and N on Ionic Cyclic C arbaphosphazene and of a C o b alt(III)phosphazene Com plex Jochen E llerm ann3 *, Jörg S u tter3, Falk A. K noch3, M atthias M oll3, W alter B au e rb Reaction of Ph2 P -N -P (P h 2) -N -(Ph2)PCoP(Ph2) -N -P (P h 2) -N -PPh2 (1) in CH2 C12 with benzimidazole yields (CH2 -PPh2 = N -PPh2 = N -PPh2)+C l" ([4]+C L). The salt [4]+BPh4" has been prepared in THF by metathesis of [4]+C l_ with N aBPh4. D eprotonation of the cationic ring in [4]+BPh4_ was accomplished using l,8-diazabicyclo[5.4.01 7 ]undec-7-ene and resulted in the six-membered carbacyclophosphazene CH=PPh2 -N = P P h 2 -N = P P h 2 (6). Treating 1 with 8 -hydroxyquinoline in CH2 C12 yields the octahedral c/s-complex (N 0) 2 CoP(Ph2) -N -P (P h 2) -N -P P h 2 (7) (N O = 8 -oxyquinolinate group). The com ­ pounds [4]+BPh4~, 6 and 7 are characterized by their IR, Raman, 3 1 P{1H) NM R, 1 3 C{1 H} N M R , !H NMR and mass spectra. Crystals suitable for X-ray structure analyses have been obtained for [4]+BPh4_ and_7x0.5 CH2 C12. The colourless plates of [4]+BPh4_ crystallize in the triclinic space group P I, with the lattice constants a = 1172.7(3), b = 1326.2(3), c = 1806.1(6) pm; a = 100.79(2), ß = 103.71(3), y = 108.18(2)°. The black blocks o f 7 x 0 .5 C H 2 C12 crystallize in the monoclinic space group P 2 x!c with the lattice constants a = 1159.0(10), b = 2008.9(10), c = 2034.6(12) pm; ß = 105.86(5)°.

 Title    Darstellung und Strukturen von 2,2,4,4-Tctrafluor-l,3-diphosphctancn und -1,3-diphosphetan-disulfiden Synthesis and Structures of 2,2,4,4-Tetrafluoro-l,3-diphosphetanes and of -1,3-diphosphetane Disulfides  
 Abstract    A simple route to 1,3-diphosphetanes [RPCF2]2 [R = Ph, Me, Bu'] is described. The phos-phaalkene intermediates RP=CF2, as well as the corresponding disulfides [R (S)PC F2]2 have been characterized. The crystal structures of [PhPCF2]2, and of the sulfides [Ph(S)PCF2]2 and [Bu'(S)PCF2]2 are reported.

The Crystal Structure of [(Et2 S)WCl4 (M e3Si -C = C -(C H 2)4-C ^ C -SiMe3) WCl4 (SEt2)] The diyne complexes [(Et2S)W C l4(R -C ^ C -(C H 2)" -C = C -R)W C l4(SEt2)] (R = SiM e3, n = 3, 4, 8; R = C6H 5, n = 4, 8) have been prepared by the reaction o f /rarcs-[WCl4(SEt2)2] with the corresponding diyne in toluene solutions. The com plexes form green or orange, diamagne­ tic, moisture sensitive crystal powders, which were characterized by their IR and 13C NM R spec­ tra. The crystal structure of the com plex with R = SiM e3 and n = 4 has been determined.
