英文摘要：

A novel Cu （I） complex [ Cu4I4L2] [ L = 2-methylpyridyl pyrimidyl sulfide ] has been synthesized through solution diffusion method and characterized by single crystal X-ray diffraction and IR spectrum. The title complex crystallizes in monoclinic crystal system with P21/n space group with a = 1.00470（5） nm, b =0.89304（4） nm, c=1.81598（8） nm, β =99.847（10） °, V=1.605 36（13） nm3, Z =2, and Mr = 1 196.40. The tetra-nuclear structure is composed of the molecule [Cu4I4L2] and its three-dimensional nets are constructed ultimately by supra-molecule weak interactions including hydrogen bond, S…S and π-π interaction.
