Abstract

 ÃƒÆ’¯Â»Â¿Single crystals of monocyclic β-lactam derivatives, I and II were grown by slow evaporation method at room temperature. Crystallographic data set for I (C24H23NO3 ) was collected with D8 Venture Dual Source 100 CMOS diffractometer at 100K using ϕ and ω scans methods while that for II (C32H26N2 O2 ) was collected with a Nonius Kappa CCD diffractometer. Single crystal X-ray diffraction analysis revealed that both compounds I and II crystallize in monoclinic crystal system with space group P21/c. The final R-factors for model structures were converged to 3.79 and 5.72%, respectively.
