Unusual μ2- and μ3-coordination modes of melamine are found in two organic−inorganic hybrid copper halides, [Cu2Br2(MA)]n (1) and [Cu3Cl3(MA)]n (2) (MA = melamine), in which the MA ligand affords two N-heterocycle N atoms to link (Cu2Br2) stairs and serves as a novel μ3 bridge to give a 3D framework, respectively.
