“…The dihedral angle between the planes of the carbazole ring systems is 85.12 (5) . Bond distances and angles of the carbazole ring systems (Table 1) are in agreement with each other, as well as with those of related dicarbazoles reported in the literature (Baker et al, 1991;Asker & Masnovi, 2005). The interior angles at the C3 [119.0 (3) ] and C3 0 [118.7 (3) ] centers attached to the methylene group are about 2 smaller than those at the C6 [121.0 (4) ] and C6 0 [121.4 (4) ] centers.…”

“…Single-crystal X-ray studies on several of these dimers have also been reported (Baker et al, 1991). Recently, we have reported the crystal structure of 1,3-bis(9-ethylcarbazol-3yl)propane as a model of poly(3-vinylcarbazole) (P3VK), a structural isomer of PVK (Asker & Masnovi, 2005). We report here the structure of the title compound, (I), another bichromophoric model compound of P3VK.…”

“…The carbazolyl substituents show an anti conformation with respect to the C12-C12 0 bond. The geometric parameters in (I) are unexceptional and agree with those of related dicarbazoles reported in the literature (Baker et al, 1991;Asker & Masnovi, 2005). The torsion angles C9a-N-C10-C11 [À86.0 (7) ] and C9a 0 -N 0 -C10 0 -C11 0 [84.0 (7) ] indicate that the N-ethyl substituents are almost perpendicular to the carbazole planes.…”

“…Bü üç yöntemle elde edilen koordinatlara göre çizilen yapılar Şekil 2'de verilmiştir. Deneysel olarak belirlenen bağ uzunlukları ve bağ açıları literatürdeki benzer yapılı karbazol bileşiklerininkiyle uyumluluk göstermektedir [27,28]. Deneysel ve teorik olarak belirlenen bağ uzunlukları, bağ açıları ve torsiyon açıları Tablo 2'de verilmiştir.…”

“…Bileşiğin kristal yapısı tek-kristal X-ışını kırınım yöntemiyle monoklinik kristal sistemi ve P21/c uzay grubunda çözülmüştür. Bağ uzunlukları, bağ açıları ve torsiyon açıları literatürdeki benzer yapılı karbazol bileşikleri ile uyumludur [27,28]. Denesel olarak çözülen yapıdan elde edilen atom koordinatları kullanılarak yarı-deneysel PM7 ve teorik B3LYP/6−31G(d,p) metodu ile hesaplamalar yapılmış ve elde edilen minimum enerji denge geometrileri deneysel sonuçlarla karşılaştırılmıştır.…”
