Abstract
Interaction of iridium(III) nitro-aqua complexes with 1,10-phenanthroline is studied. Complex anions [Ir(phen)(NO2)4]− and [Ir(phen)(OH)(NO2)3]− are isolated in the solid phase. The complex Na[Ir(phen)(NO2)4](phen)(H2O) is structurally characterized for the first time. Crystallographic data: \(a = 8.0752(5)\acute{\overset{\circ}{\mathrm{A}}}\), \(b = 11.690(7)\acute{\overset{\circ}{\mathrm{A}}}\), \(c = 14.012(7)\acute{\overset{\circ}{\mathrm{A}}}\), α = 105.55(2)°, β = 91,99(2)°, γ = 103,71(2)° space group P-1, Z = 2, ρcalc = 1,936 g/cm3. The coordination sphere of the iridium atom has a distorted octahedral geometry. The obtained structure contains an island motif consisting of the pairs of complex anions [Ir(phen)(NO2)4]− linked to each other by sodium cations.
