Bis{1-[bis(2-aminoethyl)amino]propan-2-ol}nickel(II) bis(perchlorate).

In the title compound, [Ni(C7H19N3O)2](ClO4)2, the Ni atom, which is located on an inversion center, is hexacoordinated by six N atoms from two ligands, forming a distorted octahedron. The complex molecules are linked by N—H...O hydrogen bonding, forming a one-dimensional chain structure along the a axis, which is further hydrogen bonded with the perchlorate anion to form a three-dimensional framework. One —CH2—CH2— group is disordered over two positions; the site occupancy factors are ca. 0.6 and 0.4. [ABSTRACT FROM AUTHOR]
