Raumgruppe P21/n, Z = 4, 2117 beobachtete unabhängige Reflexe, R = 3,7%, wR = 2,9%. Gitterabmessungen bei 20°C: a = 834,0(2); b = 1600,0(3); c = 1670,0(3) pm; β = 104,19(3)°. Die Verbindung bildet ein Ionenpaar mit einem NaF-Kontakt von 234,4 pm und einem NaCl-Kontakt mit 293,4 pm; der Nitrosylligand befindet sich in trans-Stellung zum Fluorliganden des [ReFCl3(NO)(CH3CN)]−−Ions. [Na(15-crown-5)][ReFCl3(NO)(CH3CN)] Synthesis, IR Spectrum, and Crystal Structure The title compound has been prepared by the reaction of [ReCl3(NO)2(CH3CN)] with the equivalent amount of sodium fluoride in the presence of 15-crown-5 in boiling acetonitrile, forming blue crystals. They were characterized by IR spectroscopy and by an X-ray structure determination. Space group P21/n, Z = 4,2117 observed independent reflections, R = 0.037, wR = 0.029. Lattice dimensions at 20°C: a = 834.0(2), b = 1600.0(3), c = 1670.0(3) pm; β = 104.19(3)°. The compound forms an ion pair via one NaF contact of 234.4 pm and one NaCl contact of 293.4 pm; the nitrosyl ligand ist in trans-position to the F atom of the anion [ReFCl3(NO)(CH3CN)]−." @default.
