Three-Dimensional Zinc(II) Coordination Polymer with Strong Blue Fluorescent Emission Formed by Parallel Interlocking of (4,4) Two-Dimensional Networks

A novel coordination polymer, [Zn(NCS)2(L)2]·2H2O, with strong blue fluorescent emission was prepared by an assembly reaction of 1,2-bis(3pyridylmethyleneamino)ethane (L) with Zn(ClO4)2 and NaSCN. A crystallographic analysis indicates that the structure of the complex contains (4,4) two-dimensional layers, which interlock each other in parallel to form a three-dimensional framework.
