Synthesis and Characterization of a Mononuclear Zinc(II) Complex [Zn(py)_3(H_2O)_3](1,5-nds) with Three-dimensional Super-molecule Structure

The mononuclear containing N-donor ligand Zn(Ⅱ) complex [Zn(py)3(H2O)3](1,5-nds)(py = pyridine,1,5-nds = 1,5-naphthalene-disulfonate anion) with three-dimensional super-molecule structure was synthesized in water and alchhol mixed solution and was characterized by X-ray crystal diffraction,IR and elemental analysis methods.The characterization results of X-ray single crystal diffraction show that the crystal of the complex crystallized in monoclinic system with space group C2/c.The unit cell parameters include a=1.58349(14) nm,b=1.21220(11) nm,c=1.45471(16) nm,α and γ= 90°,β=98.2800(10)°,V=2.8052(4) nm3,Z=4.
