    Description / Table of Contents: Chemistry and Structural Chemistry of Phosphides and Polyphosphides. 15. Gadoliniumpentaphosphide GdP5GdP5 is formed by heating (550-800°C) of Gadolinium powder and red phosphorus with small amounts of iodine. GdP5 crystallizes monoclinic in the space group P21/m with a = 4.928, b = 9.446, c = 5.370 Å, β = 102.58° and Z = 2 formula units. GdP5 is isotypic to NdP5. The bond lengths vary between 2.161 and 2.211 Å for the P—P bonds and 2.947 and 3.014 Å for the Gd—P bonds. The 2-dimensional network of P atoms is related to connected six membered rings (boat conformation) with specific defects. GdP, is paramagnetic with μ = 7.83 B.M.
    Notes: GdP5 bildet sich beim Erhitzen von Gd-Pulver mit rotem Phosphor unter Zusatz geringer Mengen an Jod zwischen 550°C und 800°C. Die Verbindung kristallisiert monoklin in der Raumgruppe P21/m mit a = 4,928, b = 9,446, c = 5,370 Å, β = 102,58° und Z = 2 Formeleinheiten. GdP5 ist isotyp zu NdP5. Die Bindungsabstände liegen zwischen 2,161 und 2,211 Å für die P—P-Bindungen bzw. zwischen 2,947 und 3,014 Å für die Gd—P-Bindungen. Für das zweidimensionale P-Gerüst wurde ein struktureller Zusammenhang zu einem Netz kondensierter 6-Ringe (Wannenform) mit spezifischen Leerstellen gefunden. GdP5 ist paramagnetisch mit μ = 7,83 B.M.
