(2-Methyl­propane-1,2-diamine-κ²N,N′)[tris­(2-amino­ethyl)amine-κ⁴N,N′,N′′,N′′′]nickel(II) diperchlorate

In the title compound, [N(C₄H₁₂N₂)(C₆H₁₈N₄)](ClO₄)₂, the Ni^II atom is coordinated in a distorted octa­hedron by four N atoms of the tris­(2-aminoethyl)amine (tren) ligand and by two N atoms of the 2-methyl­propane-1,2-diamine (2-Mepn) ligand. The primary amino group of 2-Mepn at the C-2 position occupies the position trans to the tertiary amino group of tren. The complex cations and perchlorate anions are linked via N—H...O hydrogen bonds, forming one-dimensional zigzag chains along the [101] direction.

(1,3-Diamino­propane-κ²N,N′)[tris­(2-amino­ethyl)amine-κ⁴N,N′,N′′,N′′′]nickel(II) bis­(perchlorate)

In the title compound, [Ni(C₃H₁₀N₂)(C₆H₁₈N₄)](ClO₄)₂, the Ni^II atom has a distorted octa­hedral coordination, formed by four N atoms of the tris­(2-amino­ethyl)amine (tren) ligand and two N atoms of the 1,3-diamino­propane (pn) ligand. The tren ligand consists of three five-membered chelate rings in gauche conformations and the pn ligand consists of a six-membered chelate ring in a chair conformation. In the crystal structure, a two-dimensional network of hydrogen bonds extends parallel to the (100) plane.
