The first cyanuric acid adduct incorporated with metal complex: a novel bi-layered structure constructed by hydrogen bonds

The synthesis and molecular packing analysis of the first example of cyanuric acid adduct with the insertion of the metal complex moiety have been reported. In this compound of cyanuric acid with Cu(pic)2(H2O) in a 2:1 ratio (Hpic = picolinic acid), cyanuric acid forms molecular tapes through the formation of strong cyclic N–H⋯O hydrogen bonds between the adjacent molecules. These tapes are further arranged in layered structure by hydrogen bonds such that the guest molecules (metal complex, Cu(pic)2(H2O)) are being incorporated between the tapes. The layers are organized in pairs by hydrogen bonds into novel bi-layered structure.
