摘要
The reactions of N-donor ligands 2,2-bipyridine and 1,10-phenanthroline with Cd(NO3)2路4H2O or Zn(NO3)2路3H2O in N,N鈥?dimethylacetamide in the presence of H3PO3 or H3PO4 lead to the formation of Cd(HPO3)2(bpy) (trong class="boldFont">1 trong>), [Zn4(HPO4)2(H2PO4)2(phen)4][(NO3)2]路4DMA (trong class="boldFont">2 trong>), Cd(H2PO3)(phen)2(NO3) (trong class="boldFont">3 trong>) complexes. The structure of complex trong class="boldFont">1 trong> consists of chains resulting from the 鈥渉ead to tail鈥?connection of 8-membered Cd2O4P2 rings, with two 鈥渉anging鈥?pyridine groups attached to each CdII center. Complex trong class="boldFont">2 trong> comes into being through the alternating arrangement of [Zn4(HPO4)2(H2PO4)2(phen)4]2+ cationic layers and the anionic layers constructed by isolated nitrate groups and DMA molecules. In complex trong class="boldFont">3 trong>, two phenanthroline moieties, a nitrate group, and one H2PO3 fragment appending to CdII centers generate a supramolecular aggregate. Luminescent properties of all complexes have been investigated. In particular, we present a rare example that supermolecular complex trong class="boldFont">2 trong> is used as luminescent probes to detect small molecules.
