چکیده مقاله:
The structure of title compound, C12H7N2O2 +.(NO3)−, (I), has been studied by single crystal x-ray diffractometer, xcalibur3. It is a new structure of the mono N-protonated1,10-phenanthroline-5,6-dione (Hphendione), that has a monoclinic system with C2/c space group and unit cell parameters a = 14.4860(19) Ǻ, b = 12.5177(13) Ǻ,c = 13.4535(16) Ǻ, α and γ = 90.00ο, β = 101.720(12)ο and Z = 8. The nitrate ions are connected through a relatively strong hydrogen bands to the protonated nitrogen ofthe Hphendione cations (N1—H1…O5, 2.703 (4) Å), and the weak C–H…Ohydrogen bonds between the nitrate anions and its neighbor Hphendione cations, forms an approximately layer structure for (I), that shows a small deviation from planarity, due to the protonation in one of the pyridily ring
