grid-like supramolecular layer network. The π⋯π interactions between the bpy molecules are observed between the supramolecular layers; (iii) in compound 3, two hydroxylimino groups for the dcpth I molecules link first the Zn2+ ions into a dimer, which can be viewed as a tetrahedral node. The dcpth II molecules act as the linkers, extending the tetrahedral nodes into another 1-D double-chain structure,

氨基之间的N–H⋯O相互作用,两条这样的双链会聚在一起形成一维超分子链。phen分子分布在超分子链的外侧,阻碍了1-D超分子链的进一步延伸。(ii)化合物2表现出1-D之字形单链结构。通过酰基
氨基之间的氢键相互作用,化合物2自组装成二维(2-D)网格状超分子层
