- Abstract
The crystal structure of [CuII(SSC)Cl]2·CH3OH·2H2O (SSC = salicylaldehyde semicarbazone anion) was determined by the single crystal X-ray diffraction method at 293 K. Crystal data for Cu2C17H24Cl2N6O7: a = 10.272(2) Å, b = 10.297(2) Å, c = 11.462(2) Å, α = 82.860(3)°, β = 78.384(3)°, γ = 81.330(2)°, triclinic, space group P1¯, Z = 2, d calc = 1.769 g/cm3, R 1 = 0.038. One N and two O atoms of SSC− occupy three coordination sites around Cu(II). The fourth site is occupied by Cl− to yield distorted square-planar environment. Two molecules of the complex form a planar dimer through intermolecular N-H⋯O hydrogen bonds. The most striking feature of the crystal structure is the packing of the planar dimers within the crystal. The interplanar distances between adjacent two layers are 3.280 Å, indicative of strong π-π noncovalent interactions. The methanol solvent and water molecules are included as additional components in the crystal.
