The tris(1,2-diaminoethane)nickel(II) complex was found to be a novel structure-directing agent for the preparation of the chabazite-like AlPO4-34 molecular sieve. During crystallization the complex undergoes a ligand exchange, thus helping stabilization of the AlPO4's chabazite structure by hydroxyls that have exchanged one 1,2-diaminoethane (en) molecule from the Ni(II) coordination sphere. The exchanged complex, [Ni(en)2(OH)2], remains in the chabazite host causing a triclinic deformation of the rhombohedral chabazite framework. Upon calcination the triclinic phase completely transforms into the rhombohedral chabazite-like AlPO4-34 as evidenced from the in situ XRD pattern.
