    Description / Table of Contents: Pseudochalkogeno Compounds. XX. Pseudochalkogenolysis Reactions with HexachlorocyclotriphosphazeneReactions of hexachlorocyclotriphosphazene, P3N3Cl6, with cyanamide, NH2CN, in the presence of triethylamine as well as with sodium malondinitrile, NaCH(CN)2, are described, which are leading to mixed chloro hydrogenpseudochalkogeno cyclotriphosphazenes of the types P3N3Cl4(YH)2 and P3N3Cl2(YH)4 (Y : NCN, C(CN)2). The new compounds are characterized on the basis of their n.m.r. and i.r. spectra; possible tautomerie equilibria are discussed.
    Notes: Es werden Pseudochalkogenolyse-Reaktionen von Hexachlorocyclotriphosphazen, P3N3Cl6, beschrieben, die bei Umsetzungen mit Cyanamid, NH2CN, in Gegenwart von Triethylamin oder mit Natrium-malondinitril, NaCH(CN)2 zu gemischten Chloro-hydropseudochalkogeno-cyclotriphosphazenen der Typen P3N3Cl4(YH)2 und P3N3Cl2(YH)4 (Y:NCN, C(CN)2) führen. Die neuen Verbindungen werden anhand ihrer NMR- und IR-Spektren charakterisiert; mögliche Tautomerie-Gleichgewichte werden diskutiert.

    Description / Table of Contents: Nitrosodicyanomethanide Complexes of Palladium(II) and Platinum(II)Synthesis and structure of nitrosodicyanmethanide complexes of the types [(C6H5)4P]2[M{NOC(CN)2}4] and M{NOC(CN)2}Cl{P(C6H5)3}2 as first nitrosodicyanmethanide derivatives of the metals of the platinum group, being hitherto described, are reported. Infrared investigations are indicating the coordination of the anionic pseudohalide ligand [NOC(CN)2]- in all cases via nitroso-nitrogen.

    Description / Table of Contents: Pseudochalkogen Compounds. XVI. Infrared-spectroscopic Investigations of Cyanamidomonophosphates, [PO4-n(NCN)n]3-Infrared spectroscopic investigations of trisodium cyanamidomonophosphates of the general type Na3[PO4-n(NCN)n] · aq (n: 1, 2, 3) are reported. The vibrational spectra of the compounds are confirming very clearly the special position of cyanamidophosphates within the group of substituted phosphates: Cyanamidophosphates are characterized by a full participation of pseudochalkogen groups representing NCN substituents into the mesomeric system of the anions and an only slight shortening of the P—O distances in comparision to [PO4]3-. Characteristic frequencies between 970 and 1150 cm-1 are attributed to v(PO4-nNn)-stretching frequencies. A partial 15N labelling of the monocyanamidophosphate anion, [PO3NCN]3- leads to some splitting or shifting of frequencies being connected with vibrations of the NCN group; isolated v(P—N) stretching frequencies cannot be found.
    Notes: Es wird über infrarot-spektroskopische Untersuchungen an Natriumcyanamido-monophosphaten der allgemeinen Formel Na3[PO4-n(NCN)n] · aq (n: 1, 2, 3) berichtet. Die Schwingungsspektren der Verbindungen bestätigen sehr deutlich die Sonderstellung der Cyan-amidophosphate unter den substituierten Phosphaten: Cyanamidophosphate sind durch die Einbeziehung der Pseudochalkogen-Charakter aufweisenden NCN-Gruppen in das mesomere Bindungs-system der Anionen mit einer nur geringen Verkürzung der verbleibenden PO-Bindungslängen im Vergleich zu PO43- geprägt, charakteristische Frequenzen zwischen 970 und 1150 cm-1 werden r(PO4-nNn)-Valenzschwingungen zugeordnet. Eine partielle 15N-Markierung der Cyanamid-Gruppe in Monocyanamidophosphat, [PO3NCN]3- führt zu Aufspaltungen oder Verschiebungen der mit Schwingungen der NCN-Substituenten verbundenen Frequenzen, isolierte v(PN)-Valenzschwingungs-banden scheinen nicht aufzutreten.

    Description / Table of Contents: Reactivity of PCl5 with Transition Metal Carbonyls and PhosphidesMoP2 reacts with 8 equivalents of PCl5 to MoCl4, which may be isolated in form of MoCl4(CH3CN)2. The reaction of PCl5 with M(CO)6 (M = Mo, W) depends on the solvent. Thus MoOCl3 · POCl3 was obtained in CCl4 whereas in CH3CN the compounds WCl4(CH3CN)2, MoCl3(CH3CN)4, mer-MoCl3(CH3CN)3, fac-MoCl3(CH3CN)3 and [Kat]+[MoCl4]- · nCH3CN ([Kat]+ = [PCl4]+, n = 6; [Kat]+ = [PPN]+, n = 4), respectively, are isolated depending on the amount of PCl5. The structure of the products is discussed on the basis of the IR- and Raman spectra and of magnetic moments.
    Notes: MoP2 reagiert mit 8 Äquivalenten PCl5 unter Bildung von MoCl4, welches als MoCl4(CH3CN)2 isoliert werden kann. Die Reaktion von PCl5 mit M(CO)6 (M = Mo, W) ist lösungsmittelabhängig. Während in CCl4 das MoOCl3 · POCl3 isoliert wird, führt die Umsetzung in CH3CN in Abhängigkeit von der Menge an PCl5 zu WCl4(CH3CN)2 bzw. MoCl3(CH3CN)4, mer-MoCl3(CH3CN)3, fac-MoCl3(CH3CN)3 und [Kat]+[MoCl4]- · nCH3CN ([Kat]+ = [PCl4]+, n = 6; [Kat]+ = [PPN]+, n = 4). Die Struktur der erhaltenen Produkte wird anhand der IR- und Ramanspektren bzw. von magnetischen Messungen diskutiert.
