Synthesis, crystal structure, and characterization of novel 1D Zn(II) and 2D Cu(II) coordination polymers with 1,3-bis-(1,2,4-triazol-1-ylmethyl)-2,4,6-trimethyl-benzene

摘要

Two novel coordination polymers [Zn(L)(N3)2] · H2O (1) and [Cu(L)2(Br)2] · C2H5OH · 1.5H2O (2) have been synthesized and structurally characterized. The X-ray crystal structures reveal that 1 is constructed of an infinite 1D zigzag chain and 2 contains a 2D (4,4) coordination layer. The coordination counter anions $ {text{N}}^{ - }_{{text{3}}} $ have a great impact on the structure of the coordination polymers with the flexible organic ligand L. 1 shows a strongly fluorescent emission. ESR and magnetic properties of the Cu(II) complex were also investigated.
