Abstract

Interaction of iridium(III) nitro-aqua complexes with 1,10-phenanthroline is studied. Complex anions [Ir(phen)(NO 2 ) 4 ] and [Ir(phen)(OH)(NO 2 ) 3 ] are isolated in the solid phase. The complex Na[Ir(phen)(NO 2 ) 4 ](phen)(H 2 O) is structurally characterized for the first time. Crystallographic data: a= 8.0752 (5) Ǻ, b= 11.690 (7) Ǻ, c= 14.012 (7) α, α = 105.55(2)°, β = 91,99(2)°, γ = 103,71(2)° space group P-1, Z = 2, ρ calc = 1,936 g/cm 3 . 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)(NO 2 ) 4 ] linked to each other by sodium cations.
