M r = 313.11, orthorhombic space group Pbca, a = 8.165(1), b = 9.491(2), c = 32.207(5) Å V = 2496(1) Å 3 , D X = 1.667 Mgm −3 , Z = 8, F(000) = 1248, λ(MoKα) = 0.71069 Å, μ = 32.7 mm −1 . The crystal structure was determined by direct methods and refined by least‐squares procedure to the discrepancy factor R = 0.065. Positions of hydrogen atoms were calculated. The structure determined by x‐ray analysis confirms the chemical results.
