Abstract:

Light green crystals of the Ni (II) complex material, [Ni(H2O)6](C14H16N2O6S2), were obtained by the self-assembly of Ni(H2O)6·6H2O, 4-amino-3-methyl-benzenesulfonic acid and NaOH. The result of X-ray diffraction shows that each Ni (II) atom is six-coordinated in a distorted octahedral environment by six oxygen atoms from the water molecules. The complex molecules are connected by hydrogen bonds to form two dimensional network structure. The thermal analysis shows that the complex has a enothermic peak at 302 C, indicating that coordinated water molecules are in the complex.
