N-(4,5-Diazafluoren-9-ylidene)aniline

“…In the molecule of (I) ( Fig. 1), the bond lengths (Allen et al, 1987) and angles are within normal ranges, which are comparable with the corresponding values in other fluorenylidene compounds (II), N-fluorenylidene-aniline-benzene (4/1), (III) (Peters et al, 1998), N-(9H-fluoren-9-ylidene)-N-(4-methoxyphenyl)amine, (IV) (Glagovich et al, 2004a) and N-9H-fluoren-9-ylidene-3,4-dimethyl-aniline, (V) (Glagovich et al, 2004b). Rings A (C1-C6), B (N2/C8-C12), C (C7/C8/C12/C13/C17) and D (N3/C13-C17) are, of course, planar.…”

N-(9H-Fluoren-9-ylidene)-4-methylaniline

“…In the title compound ( Fig.1), the C12-N1-C14 angle of 120.76 (15)° and the N1-C12 bond distance of 1.278 (2)Å are in close agreement with the similar Nfluorenylideneaniline (Glagovich et al, 2004;Peters et al, 1998;Pierre et al, 1997). The fluorene unit is essentially planar and the benzene ring bound to the imine N atom bears a methyl that is nearly coplanar.…”

“…The title compound was obtained from the condensation reaction of 9-fluorenone and 4-methylaniline as described in literature (Glagovich et al, 2004) and recrystallized from ethanol solution at room temperature to give the desired product as yellow crystals suitable for single-crystal X-ray diffraction.…”
