Abstract

In this study by synthesising 1-[N-(4-fluorophenyl)]naphthaldimine a Schiff base molecule a single crystal has been obtained. Intensity data obtained with a diffractometer X-ray single crystal were collected and by using SHELXS-97 and SHELXL-97 programs the crystal structure has been solved and refined. The crystal system is monoclinic and space group $P2_1{/^a}$ and other parameters are a=6.998(3), b=13.998(4), $c=13.050(4)AA$ ve $beta=92,850(1)^0$, $V=1275,0(4)AA^3$, Z=4,$D_c=l,382 g.cm^{-3}$, , u.(MoKtt)=0.096 mm'1 and R=0.048 for 1326 reflections $1>2sigma(I)$. Intramolecular hydrogen bond length is found $2.547(3)AA$. The results obtained from X-ray diffraction data the molecule is concluded a phenol-imine tautomeric form.

Özet

Bu çalışmada bir Schiff bazı olan 1-[N-(4-florofenil)]-2-hidroksi-1-naftaliden molekülü sentezlenerek tek kristali elde edilmiştir. X-ışını tek kristal difraktometresiyle veriler toplanmış, bu veriler kullanılarak SHELXS-97 ve SHELXL-97 programları yardımıyla kristalin yapısı çözülmüştür. Kristal sistemi monoklinik uzay grubu $P2_1{/^a}$ olup diğer parametreler a=6,988(3), b=13,998(4), $c=13,050(4)AA$, $beta=92,850(1)^0$ , $V=1275,0(4)AA^3$, Z=4, $D_c=l,382 g.cm^{-3}$, $mu(MoKalpha)=0,096 mm^{-1}$ ve $1>2sigma(I)$ şartını sağlayan 1326 yansıma için R=0,048 olarak elde edilmiştir. Molekül içi hidrojen bağının uzunluğu ise $2,547(3)AA$ bulunmuştur. X-ışınları kırınım deneyleri sonuçlarına göre molekül enol tautomerisine sahiptir.
