 Title    und 5.10-Dihydro-5.10-diethylphenaziniumtriiodid  
 Abstract    Molecular and Crystal Structure of 5.10-Dihydro-5,10-dimethylphenaziniumtriiodide and 5,10-Dihydro-5,10-diethylphenazinium triiodide Oxidation of 5,10-dihydro-5,10-dimethylphenazine and 5,10-dihydro-5,10-diethyl-phenazine under different reaction conditions leads to several iodine containing solids. The preparation and X-ray structure of two of them, 5,10-dihydro-5,10-dimethyl-phenaziniumtriiodide (3) and 5,10-dihydro-5,10-diethylphenaziniumtriiodide (4) are reported here. Compound 3 crystallizes in space group P 2i/n with lattice parameters a = 8.552(6) A, b = 16.953(2) A, c= 12.157(9) A and ß= 103.46(2)° with four formula units in the unit cell. The structure was refined to an i?-value of 0.046 using 2387 independent reflections. The lattice constains distinct, slightly distorted triiodide ions and bent 5,10-dihydro-5,10-dimethylphenazinium radical cations. Compound 4 crystallizes in the same space group P2i/n with lattice parameters a = 8.531(6) A, b = 8.332(21) A, c = 13.320(15) A and ß— 94.44(19)° with two formula units in the unit cell. The structure was refined to an i?-value of 0.076 using 1195 independent reflections. The lattice contains strictly linear symmetrical triiodide ions and planar centrosymmetrical 5,10-dihydro-5,10-diethyl-phenazinium radical cations.
