Synthesis, crystal structure and fluorescence of a new triazolated-bridged 2-D coordination polymer

In the 2-D coordination polymer [Zn(L)Cl]n (HL = 3-amino-1H-1,2,4-triazole) synthesized by diffusion method, L− ligands link Zn2+ to form 6- and 16-membered rings. The interconnection of the two kinds of rings results in a 2-D network, which features a (4,82) topological network. Hydrogen bonds connect the neighboring plane-symmetry layers into a 3-D framework. The fluorescence with emission at 416 nm is assigned to LMCT.
