Abstract
Bu çalışmada, C21H19N3OS (I), C17H22N2S (II) ve C19H25N3O (III) yapı analizleri X-ışını kırınımı yöntemi ile belirlenmiştir. Kristallerin verileri, STOE ?PDS ?? difraktometresi ile toplanmıştır. Yapılar, SHELXS-97 programı yardımı ile direkt yöntemler kullanılarak çözülmüş ve SHELXL-97 programı yardımı ile en küçük kareler yöntemi ile arıtılmıştır.C21H19N3OS (?), molekülünün birim hücre parametreleri, a=5.757(5)Å, b=16.762(5)Å, c=18.676(5)Å' dur. Bu kristalin birim hücresi ortorombik P 2 2_1 2_1 uzay grubuna aittir. Arıtım sonucunda (?) molekülünün güvenilirlik faktörü (R), 0.0842 olarak belirlenmiştir. Molekül, N?H?O, N?H?N, C?H?O, C?H?S olmak üzere dört adet molekül içi hidrojen bağına sahiptir. (I) molekülü moleküller arası bir tane O?H?S hidrojen bağına sahiptir.C17H22N2S (?I), molekülünün birim hücre parametreleri, a=6.3972(4)Å, b=9.4988(6)Å, c=26.016(2)Å, ß=93.496(2)°' dir. Bu kristalin birim hücresi monoclinic P ? 1 2 ? _1?c 1 uzay grubuna aittir. Arıtım sonucunda (??) molekülünün güvenilirlik faktörü ( R ), 0.2150 olarak belirlenmiştir. (II) molekülü moleküller arası bir tane N?H?N hidrojen bağına sahiptir.C19H25N3O (?II), molekülünün birim hücre parametreleri, a = 31.4660(17) Å, b= 11.2140 (7) Å, c = 10.0710 (8) Å' dur. Bu kristalin birim hücresi ortorombik P c c n uzay grubuna aittir. Arıtım sonucunda (III) molekülün güvenilirlik faktörü (R), 0.2141 olarak belirlenmiştir. Molekül, bir adet C?H?O molekül içi hidrojen bağına sahiptir. (III) molekülü moleküller arası bir tane O?H?N hidrojen bağına sahiptir.Anahtar kelimeler: X-Isını Kırınımı, Schiff Bazı, Tiyazol, İmidazol, Oksim.
In this study, the structure analysis of C21H19N3OS, C17H22N2S and C19H25N3O have been determined by the method of X-ray diffraction.
