Data were collected on d Stoe-Siemens diffractometer in the range 8 ' S 20 I 50-(6793 reflections collected, 4926 independent reflections). The structure was solved by direct methods [12] and refinement, based on F 2 , was by full-matrix leastsquares techniques [13] (all non-hydrogen atoms were refined anisotropically and hydrogen atoms were included in calculated positions) to R , = 0.0428, wR2 = 0.1022 for 4040 unique reflections [ F > 4o(F)j. -Xray crystal data for 4: C,,H,,N,OLi,.
