Abstract: The title compound crystallizes in the trigonal system and in the P3 space group. The unit cel parameters are a = b = 2 717.1(8) pm, c = 1 222.5(3) pm, V = 7 816 . 106 pm3. Z = 18 density calculated Dc = 0.995 Mg m-3. Radiation used CuKα, λ = 154.18 pm, intensities measured at room temperature. Mr = 260.34, linear absorption coefficient μ = 0.342 mm-1, F(000) = 2 520. Final R = 0.077 for 3 096 observed independent reflections. There is an unusual number of six isomers in the asymmetric unit. The structure is b…
