摘要

A zinc(Ⅱ) complex [Zn(bdc) (py). H2O]n (bdc = 1,4-benzenedicarboxyiate, py = pyridine) has been prepared ana characterized. Single crystal X-ray diffraction analysis reveals that the complex crystallizes in the monoclinic space group P21/n with a= 0.84823(3), b = 0.91440(3), c = 1.65141(2) nm, β = 91.243(2)°, V = 1.28057(6) nm3, z = 4. The coordination geometry at each Zn(Ⅱ) center is a distorted tetrahedron. Two independent bdc ligands in a herringbone pattern link alternatively four-coordinated Zn(Ⅱ) centers into a one-dimensional polymeric chain. Hydrogen bonds among coordinated water molecules and uncoordinated oxygen atoms of two independent bdc ligands from different polymeric chains extend one-dimensional polymeric chains into a three-dimensional structure.
