Hydrothermal synthesis, crystal structure and strong blue fluorescence of a novel 3D coordination polymer containing copper and zinc centers linked by isonicotinic acid ligands

The three dimensional structure of 1 has a novel topological metal-organic framework, which is built up by Zn2+, Cu+ and ligands IN to generate an open-framework with an unusual helical [–Zn(cu)-IN–]n chains along the b axis.
