Abstract: Two nitronyl nitroxide radical NIT2PhMe2 (1), 2,5-dimethyl-1,4-bis(nitronyl nitroxide) benzene and NITPhNMe3·I·H2O (2), hydrous iodide m-N,N′,N″-trimethyl-benzenaminium nitronyl nitroxide, have been synthesized and structurally characterized. The compound 1 crystallized in monoclinic, space group P21/c with a=0.613 7(4) nm, b=1.766 2(12) nm, c=1.180 9(6) nm, β=117.66(3)°, V=1.133 7(13) nm3, Mr=416.52, Z=2 and F(000)=456. The compound 2 also crystallized in monoclinic, space group P21/c with a=1.143 47(11) nm, b=1.119 09(11) nm, c=1.527 38(15) nm, β=101.766(2)°, V=1.9134(3) nm3, Mr=436.31, Z=4 and F(000)=884. Through the weak hydrogen bond, 1 and 2 form three-demensional supramolecular networks, respectively. CCDC: 749328, 1; 749329, 2. |
