Year 2004, Volume: 5 Issue: 2, 329 - 337, 01.05.2004

Abstract

In this study in order to the geometry optimization of the 2-acetylamino-6-benzoyl-4-chlorophenol crystal, which is used for forming analgesic and antienflamatuar medicine and of which crystal structure was determined using x-ray diffraction method, PM3, AM1 and MNDO semi emprical molecular orbital methods found in the HyperChem program were used. By the geometry optimization geometric parameters of the molecules having the minimum energy were found. These values which were theoretically obtained were compared with the emprical values obtained by x-ray diffraction method. These results showed that for the C15found to be consistent with the emprical x-ray diffraction data. By geometry optimization using PM3, AM1 and MNDO methods relevant energy values of the molecular structures were calculated

Abstract

Bu çalışmada; analjezik ve antienflamatuvar ilaçların yapımında kullanılan ve kristal yapısı x-ışını kırınım yöntemi ile çözülen 2-asetilamino-6-benzoil-4-klorofenol C H NO Cl 15 12 3 kristaline, HyperChem paket programında bulunan yarı deneysel moleküler orbital yöntemlerden PM3 Parametric Model 3 , AM1 Austin Model 1 ve MNDO Modified Neglect of Diatomic Overlap yöntemleri kullanılarak geometri optimizasyonu yapıldı.Geometri optimizasyonu ile moleküllerin minimum enerjiye sahip geometrik parametreleri elde edildi. Teorik olarak elde edilen bu parametreler, deneysel olarak elde edilen x-ışını kırınım değerleri ile karşılaştırıldı. Bunun sonucunda C H NO Cl 15 12 3 kristalinde bağ uzunluk ve bağ açılarında AM1 yönteminin deneysel x-ışını kırınımı sonuçları ile daha uyumlu olduğu görüldü. Moleküler yapının PM3, AM1 ve MNDO yöntemlerine göre geometri optimizasyonu sonucu, ilgili enerji değerleri hesaplandı.
