Preparation and X-Ray Crystal Structure of Layered Ca(II) Complex Material
A novel Ca(II) complex material was prepared by reaction of O-nitrobenzaldehyde- 3-amino-benzenesulfonic acid with Ca(ClO4)2, and characterized by X-ray single crystal diffraction method. The analytical results shows that the Ca(II) complex was crystallized in the monoclinic system, space group P2(1)/c, with a = 17.515(10) Å, b = 7.019(4) Å, c = 13.853(8) Å, β = 104.855(10) º, V = 1646.3(17) Å3, Z = 2. The geometry of Ca(II) is a slightly distorted dodecahedrall geometry. In the crystal packing, the complex molecules form layered structure by the π-π packing interaction, and the molecules form a one-dimensional chain structure by hydrogen bonds.
