文摘

Synthesis, characterization, and crystal engineering of a tris chelate compound, [NiIIL₃](N₃)Cl (1), (L = diequatorial trans-1,2-diaminocyclohexane) have been described. The compound crystallizes in the cubic P4₃32 space group with a = 13.859(12) ? and Z = 4. In this structure, the azide anion is highly disordered. Each chloride in 1 interacts with six amine hydrogens and is surrounded by three mononuclear cations, each of which, in turn, are linked with three chlorides to form a three-dimensional channel network. This is the first report of hexafurcated (acceptor) N–H ⋅s Cl− hydrogen bonds in metalloorganic systems and the first report of the three-dimensional framework resulted basically due to the multifurcated acceptor nature of the halide anion.
