Die Kristallstruktur des Oxophosphazens [Ph₃PNPPh₂NP(O)Ph₂]

Abstract

Crystal Structure of the Oxophosphazene [Ph3PNPPh2NP(O)Ph2] Single crystals of [Ph3PNPPh2NP(O)Ph2] were obtained as a by‐product from the synthesis of [NaNPPh3]6 as a result of partial hydrolysis. According to the crystal structure determination the compound forms a molecular structure with a PNPNP chain with PN distances between 155.3(6) and 159.8(5) pm and PNP bond angles of 143.2(4) and 140.7(4)°. Space group P1¯, Z = 2, lattice dimensions at 213 K: a = 922.7(1); b = 1040.1(1); c = 1908.0(1) pm; α = 90.55(1)°; β = 103.01(1)°; γ = 92.87(1)°; R = 0.0859.
