Abstract
- Two cadmium(II) arenedisulfonate complexes, namely [Cd(Him)4(H2O)2][Cd(Him)4(2,6nds)2] (1) and Cd(Him)4(1,5nds)]n (2), where Him = imidazole, nds = naphthalenedisulfonate, have been synthesized in aqueous solution and characterized by elemental analysis, IR spectra, and X-ray single-crystal diffraction. Crystal data for 1: C44H48O8N16S2Cd2, triclinic P -1, a = 8.466(2), b = 9.957(3), c = 17.911(5) Å, α = 79.999(5)○, β = 89.918(5)○, γ = 68.740(5)○, Z = 1, R1 = 0.0228, wR2 = 0.0568. Crystal data for 2: C22H22O6N8S2Cd, monoclinic Cc, a = 9.854(5), b = 17.122(9), c = 15.809(8) Å, β = 100.700(8)○, Z = 4, R1 = 0.0171, wR2 = 0.0420. The crystal structures of two complexes were elucidated and are all directed by hydrogen bonding interactions. Complex 1 features a 3D supramolecular framework generated by H-bonded 2D-sheet, and complex 2 also displays a 3D network formed by H-bonded 1D [Cd(Him)4(1,5-nds)]n polymeric chains. Furthermore, in the two complexes, the arenedisulfonate anions act as bifunctional spacers to compete with water molecules for the Cd(II) coordination by employing imidazole as auxiliary ligand.
