Abstract

The crystal and molecular structure of the molecular nitrogen complex azidodinitrogenbis(ethylenediamine))uthenium(II) hexafluorophosphate, [Ru(N3)(N2)(NH2CH2CH2)2] [PF6], has been determined from three-dimensional X-ray data collected by counter techniques. The material is X-ray sensitive and it was necessary to use four different crystals for the data collection. The central metal atom is coordinated octahedrally to six nitrogen atoms. The Ru-N of (N2) bond distance is 1.894 (9) Å and the Ru-N-N bond angle is 179.3 (9)°; the Ru-N (of N3–) bond distance is 2.121 (8) Å and the Ru-N-N bond angle is 116.7 (7)°. ‘ The Ru-N distances to the nitrogen atoms of the ethylenediamine groups range from 2.144 (9) to 2.108 (9) Å, with an average distance of 2.125 (19) Å. Crystal data: monoclinic, space group C2h6-P21/n; a = 9.97 (1) Å, b = 12.01 (1) Å, c = 12.59 (1) Å, β = 102.4 (3)°, Z = 4; dobsd = 2.00 ± 0.03 g/cm3, dcalcd = 1.98 g/cm3. The structure was refined using 1375 independent reflections from a limited data set for which F2 > 3σ(F2), and the refinement converged to a conventional R factor (on F) of 5.6%.
