Structure of 2,2,5,5,7,7-Hexamethyl-3,6-di-t-butyl-1,3,4,6-tetraphospha-2,5,7-trisila-norbornane (me2Si)3P4(Cme3)22,2,5,5,7,7-Hexamethyl-3,6-di-t-butyl-1,3,4,6-tetraphospha-2,5,7-trisila-norbornane(me2Si)3P4(Cme3)2 crystallizes monoclinic in the space group C2/c with a = 1593.2 pm, b = 1177.5 pm, c = 1373.3 pm, ß = 111.39° and Z = 4 formula units. In the central norbornane framework the bond lengths are P—P = 221.4 pm, P—Si = 225.9 pm, respectively. The bond lengths to the substituents are P—C = 189.1 pm and Si—C = 188.0 pm. Configuration and conformation are discussed in detail.
Notes:
2,2,5,5,7,7-Hexamethyl-3,6-di-t-butyl-1,3,4,6-tetraphospha-2,5,7-trisilanorbornan (me2Si)3P4(Cme3)2 kristallisiert monoklin in der Raumgruppe C2/c mit a = 1593,2 pm, b = 1177,5 pm, c = 1373,3 pm, ß = 111,39° und Z = 4 Formeleinheiten. Im zentralen Norbonan-Gerüst sind die Abstände P—P = 221,4 pm und P—Si = 225,9 pm bzw. 229,1 pm. Zu den Substituenten sind die Abstände P—C = 189,1 pm und Si—C = 188,0 pm. Konfiguration und Konformation werden eingehend diskutiert.
