- Crystal data for 1 C72H168Cd2O24Sr2Zr4, M = 2182.98, monoclinic, space group P21/c, a = 22.720(5) Å, b = 12.838(3) Å, c = 19.320(4) Å, V = 5598(2) Å3, Z = 2, Dcal = 1.295, λ(MoKα) = 0.71073 Å, T = 293(2) K, μ = 1.728 mm−1, R1 = 0.0956. Some of the isopropyl groups suffered from disorder problems and could not be refined satisfactorily. A toluene molecule fills the void in the crystal lattice of 1.
