    Notes: (C2H10N2)3[V10O28].2H2O, tris(ethylammonium)decavanadate dihydrate, crystallizes in the monoclinic system (P21/n). Its structure, solved by single-crystal X-ray diffraction with a final R value of 0.0237 for 5136 unique reflections, is characterized by a pseudo BC arrangement of the [V10O28]6− polyanions between which are intercalated the ethylenediammonium cations and the water molecules.

    Description / Table of Contents: Magnetische Struktur von CsPd2F5Die Struktur von CsPd2F5 wird durch Neutronenbeugungsdaten an Pulverproben bestätigt. CsPd2F5 kristallisiert in der orthorhombischen Raumgruppe Imma. Die Gitterkonstanten bei 100 K sind a = 6,473(2), b = 7,853(5), c = 10,718(3) Å, und mit der Rietveld-Methode wird ein R1 = 0,020 erhalten. Die Struktur wird aus Ketten von PdF6-Oktaedern gebildet, die die eine Hälfte des Palladiums in high-spin-Konfiguration enthalten und miteinander über Quadrate verbunden sind, in denen die andere Hälfte des Palladiums in low-spin-Konfiguration vorliegt. CsPd2F5 ist unter TN = 38 K antiferromagnetisch. Im geordneten Zustand zeigt sich eine schwache ferromagnetische Komponente (σ0 = 0,098 μB bei 2 K). Die bei 4 K bestimmte magnetische Struktur ist mit den magnetischen Daten vereinbar und kann in der magnetischen Gruppe Im′m′a′ ohne eine Verdoppelung der Gitterparameter beschrieben werden. In den Ketten sind die Pd2+ antiparallel gepaart. Die magnetischen Momente sind in der (x0z)-Ebene lokalisiert, der Winkel zwischen den Momenten und der z-Achse beträgt 18°.
    Notes: The structure of CsPd2F5 has been confirmed from neutron diffraction data on powdered sample. CsPd2F5 crystallizes in the orthorhombic Imma space group. At 100 K, the unit-cell constants are a = 6.473(2) Å, b = 7.853(5) Å, c = 10.718(3) Å and the calculation carried out using the Rietveld method leads to R1 = 0.020. The network is formed of PdF6 octahedra chains containing half of Pd in high-spin configuration, connected one to each other by square planes containing the other half of Pd in low-spin configuration. CsPd2F5 orders antiferromagnetically below TN = 38 K. In the ordered state a weak ferromagnetic component occurs (σ0 = 0.098 μB at 2 K). The magnetic structure determined at 4 K is consistent with the magnetization data and can be described in the Im′m′a′ magnetic group without any doubling of the unit-cell parameters. Within the chains, Pd2+ are coupled antiparallel. The magnetic moments are located in the (x0z) plane, the angle between the moments and the z axis being 18°.
