N2 - Treatment of "ruthenium blue" in ethylene glycol with azide ions produced three ruthenium complexes having different nuclearities and oxidation states. The first, [Ru(N3)6]3- (1), a mono-nuclear RuIII hexaazide complex has been crystallized by using various counter-cations. The X-ray structure analysis of these salts has revealed a slightly distorted octahedral geometry with a Ru-N bond distance of 2.066(3) Å. The second, [Ru2N(N3)10] 6- (2), is a nitrido-bridged RuIII, RuIV complex. The Ru-N-Ru bond angle in 2 is 170.8(2)° and the N 5Ru-N-RuN5 system adopts a staggered configuration. The average Ru-N bond distances of the two metal atoms are slightly different. These parameters do not agree with the widely accepted view that most nitrido bridged ruthenium atoms have a RuNRu allene type structure. Complex 3, [(C 2H4O2)2RuN]-, a by-product of the reaction, is a RuVI complex containing a triply-bonded terminal nitride with a RuN bond distance of 1.598(3) Å.
