Synthesis and Structure of Zinc 3-Hydroxy-2-mercaptopyridine Complex, Zn（C5H4NOS）2
摘要
The zinc 3-hydroxy-2-mercaptopyridine complex was prepared by self-assemby reaction of Zn(NO3)2 and 3-hydroxy-2-mercaptopyridine (hmp). Single-crystal X-ray diffraction analysis indicates that it crystallizes in a tetragonal system, space group (No. 122) with a = 13.4562(6), c = 13.6860(8) (A。), V = 2478.1(2) (A。)3, Z = 8, Mr = 317.67, Dc = 1.703 g/cm3, μ(Mo-Kα) = 2.308 mm－1 and F(000) = 1280. R = 0.0289 and wR = 0.0676 for 1040 observed reflections (I > 2σ(I)). The crystal structure consists of a neutral molecule with a distorted tetrahedral cis-ZnS2O2 core, in which the mononuclear Zn2+ ion is coordinated by two O and two S atoms from two hmp ligands with the average bond distances of 2.301(1) (A。) for Zn-S and 1.986(3)(A。) for Zn-O. The 1H . NMR and IR spectra of the compound are discussed.
