11 SINGLE CRYSTAL X-RAY STRUCTURE DETERMINANT OF THE CnHgNOS, C13H10 Ct NO and C17H1603 MOLECULES ABSTRACT In this study, the crystal and molecular structures of (CnHgNOS) 2-[P-hydroxyphenlyyimino]-thiophene, (C13H10C £ NO) 4'-chlorobenzilidene-4- hydroxyanime crystals (known as Schiff bases) and (C17H16O3) 2-(4- methylbenzoyloxy)-5-methyl acetophenon crystal have been determined by x- ray diffraction technique. The structures were solved by direct methods and the atomic parameters were refined by full-matrix least-squares and difference- Fourier methods.

C11H9NOS molecule has three planar moieties two of which are rings, namely hydroxyphenyl and thiophene, having an angle of 20.8(1)° between them. The crystal structure is stabilized by an O-H...N hydrogen bond and C- H...0 intermolecular interactions. The C...0 intermolecular contact distance is 3,443(2)A. In Ci3İHıoC^NO molecule, O-H...N type hydrogen bond occurs between the hydroxyl and amino groups. The O...N intermolecular contact distance is 2,849(2)A. In Ci7Hi603 molecule, two types of C-H...0 interaction (intramolecular and intermolecular) were observed. Key Words: IR, Schiff bases, Cristallography, X-ray diffraction, Crystal structure.
