✦ Synopsis

&, = 0.032); equivalent reflections were merged. The structure was solved by a combination of Patterson and difference Fourier techniques. The final cycle of full-matrix least-squares refinement was based on 5784 observed reflections ( I > 3.00a(I)) and 326 variable parameters and converged (largest parameter shift was less than 0.009 times its esd) with R = 0.060 and R , = 0.063. A final difference Fourier map showed no chemically significant features. Crystal data are a = 13.084(2), b = 13.089(2), c =13.194(2) ,&,a = 60.08(1),8 = 64,78(1),y =72.88(1)", V =1762(1)A3, space group Pi, Z = 2.
