| 摘 要： | <正> The title crystal structures have been determined by X-ray diffraction. They crystallize in the monoclinic, space group P21/n, Z=4 with diaensions a= 12.388(1), b= 7.140(1), c= 14.302(1) A,β=90.65(1)° for compound Ⅰ, and a=12.987(2), b= 7.190(1), c=13.284(2) A,β=92.40(2)° for compound Ⅱ. The structures were solved by direct methods, and refined by full matrix least-squares to consistence factors R=0.026 for Ⅰ and R=0.031 for Ⅱ.
