[Ni(en)(3)] [NO3](2) undergoes a displacive phase transition from P6(3)22 at ambient pressure to a lower symmetry P6(1)22/P6(5)22 structure between 0.82 and 0.87 GPa, which is characterized by a tripling of the unit cell c-axis and the number of molecules per unit cell. The same transition has been previously observed at 108 K. The application of pressure leads to a general shortening of O H hydrogen bonding interactions in the structure, with the greatest contraction (24%) occurring diagonally between stacks of Ni cation moieties and nitrate anions.
