| Abstract: Coordination compound [Co(Hdhpmy)(H2O)3]·3H2O (H3dhpmy is 2-(4-hydroxy-6-oxo-1,6-dihydropyrimi-din-2-ylthio)acetic acid) has been synthesized by solution method and characterized by elemental analysis, IR spectra，fluorescence, and the crystal structure was determined by single-crystal X-ray diffraction. The crystal of the title complex belongs to orthorhombic system, space group Pca21, with a=0.725 36(9) nm, b=1.361 72(16) nm, c=1.386 70(16) nm, V=1.369 7(3) nm3, Z=4, Mr=367.20, Dc=1.781 g·cm-3, F(000)=756, μ=1.456, R1=0.041 9, wR2=0.075 0. The adjacent metal center is connected into one chain by weak π-π interactions between heterocyclic rings, furthermore the complex is extended into three-dimensional network by hydrogen bonds.
