<i>trans</i>-dinitro- and <i>trans</i>-dinitratorUthenium complexes [RuNO(NH<sub>3</sub>)<sub>2</sub>(NO<sub>2</sub>)<sub>2</sub>(OH)] AND [RuNO(NH<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)(NO<sub>3</sub>)<sub>2</sub>]NO<sub>3</sub>·H<sub>2</sub>O
Methods for the synthesis of <i>trans-</i>diammino complexes [RuNO(NH<sub>3</sub>)<sub>2</sub>(NO<sub>2</sub>)<sub>2</sub>(OH)] (I) and [RuNO(NH<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)(NO<sub>3</sub>)<sub>2</sub>](NO<sub>3</sub>)·H<sub>2</sub>O (II) are suggested. The compounds were studied by IR spectroscopy and X-ray phase and X-ray structural analyses. Crystal data: space group <i>P</i>-1; <i>a</i> = 6.2328(2) Å, <i>b</i> = 11.0488(3) Å, <i>c</i> = 11.0981(4) Å; α = 71.942(1)°, β = 83.291(1)°, γ = 86.877(1)° (I); space group <i>P</i>2<sub>1</sub>; <i>a</i> = 6.6290(2) Å, <i>b</i> = 13.4389(5) Å, <i>c</i> = 7.0180(2) Å, β = 114.281(1)° (II). Complex II readily lost some part of crystal water on storage in open air.
