3,3'-[(E)-ethene-1,2-diyl]di(9-hexyl-9H-carbazole]compound was synthesized in three steps beginning from 9H-carbazole and its structure was characterized via spectroscopic techniques. Its crystal structure was solved in monoclinic space group P2₁/c and geometrical properties were  compared with data obtained from PM7 and DFT/B3LYP theoretical calculations. High correlation between DFT computational and X-ray diffraction experimental results has been determined. Intermolecular associations in crystal structure have been attempted to be explained  using the calculated frontier orbitals.

3,3'-[(E)-eten-1,2-diil]di(9-heksil-9H-karbazol) bileşiğinin sentezi, X-ışını yapı tayini ve teorik yapı tahmini

Öz

3,3'-[(E)-eten-1,2-diil]di(9-heksil-9H-karbazol) bileşiği 9H-karbazoldan çıkarak üç basamakta sentezlenmiş ve yapısı spektroskopik yöntemlerle aydınlatılmıştır. Kristal yapısı monoklinik uzay grubu P2₁/c'de çözülmüş ve geometrik özellikleri yarı-deneysel PM7 ve teorik DFT/B3LYP hesaplamalarla elde edilen verilerle karşılaştırılmıştır. DFT hesapsal sonuçlar ile X-ışını kırınımı deneysel sonuçlar arasında yüksek korelasyon belirlenmiştir. Kristal yapıdaki moleküller arası etkileşimler hesaplanan öncü orbitallerle açıklanmaya çalışılmıştır.
