Abstract:
In this paper the syntheses and crystal structures of diaqua-bis(pyridine- 2-sulfonato-N,O) cadmium(II) 1 ([Cd(C5H4NSO 3)2(H2O)2]) and diaqua-bis(pyridine- 2-sulfonato-N,O) zinc(II) 2 ([Zn(C5H4NSO3) 2(H2O)2]) are reported. Complexes 1 and 2 are isostructural and belong to monoclinic with space group C2/c. Crystal data: a = 13.7671(5), b = 7.2778(3), c = 16.1559(9) Å, β = 106.656(3)°, V= 1550.8(1) Å3, Z = 4, Dc = 1.990 g/cm3, F(000) = 920, μ = 1.719 mm-1, R = 0.0225 and wR = 0.0584 for 1; a = 13.711(1), b = 7.1451(9), c = 15.972(1) Å, β = 107.079(5)°, V = 1495.7(3) Å3, Z = 4, Dc = 1.855 g/cm3, F(000) = 848, μ = 1.964 mm-1, R = 0.0310 and wR = 0.0831 for 2. The Cd atom in complex 1 and Zn in 2 are both six-coordinated by two O and two N atoms of two pyridine-2-sulfonate ligands, and two water O atoms, forming a distorted octahedral coordination geometry. The molecules in these two title complexes have a crystallographic C2 symmetry. The neighboring molecules in each complex are connected by hydrogen bonds of O-H (coordinated water molecule)⋯O(uncoordinated sulfonate), obtaining a two-dimensional supramolecular architecture.
