Document Type


Publication Date



The crystal structure of cesium 1,2,4,5-benzenetetracarboxylate has been determined by X-ray diffraction and refined by least-squares methods to R = 0.057 and Rw = 0.067 using 708 reflections. The compound crystallizes in the triclinic space group P1 with one anion in the unit cell. The lattice parameters are a = 6.8827(6), b = 7.9480(5), c = 5.1033(6) Å, α = 92.260(7), β = 104.782(7), γ = 90.970(5)° and V = 269.61 Å3. There is a very short hydrogen bond with an O...O distance of 2.42 Å. The cesium ion is ten-coordinate with a distorted bicapped square antiprism geometry of oxygens about the cesium. © 1994.
