| The bond lengths of C8-N2 and C7-N1 are 1.481(2) Å and 1.474(2) Å respectively, which are close to 1.47-1.50A, the typical C-N bond length. Because the lone pairs of N1 and N2 have p-¦Ð conjugation with benzene ring respectively, the bond lengths of C1-N2 and C6-N1 decrease to 1.430(2) Å and 1.427(2) Å. The bond length of C7-C8 is 1.514(3) Å, which is close to 1.53Å, the typical C-C bond length. The bond length of C9-O1 and C11-O2 are respectively 1.211(2) Å and 1.214(2) Å, which are close to 1.21Å-1.23Å, the C=O bond length. The lone pair electrons of N1 have p-¦Ð conjugation with double bond in C11-O2 and the bond length of C11-N1 decreases to 1.352(2)Å. The lone pair electrons of N2 have p-¦Ð conjugation with double bond in C9-O1 and the bond length of C9-N1 decreases to 1.362(2)Å. |
