The new mononuclear complex [Ni(TAMEN)](ClO 4 ) 2 ·DMF (TAMEN = N,N′‐tetra‐(4‐antipyrylmethyl)‐1,2‐diaminoethane) has been synthesized and its crystal structure was determined by single‐crystal X‐ray diffraction. It crystallizes with monoclinic symmetry, space group P 2 1 / c (no. 14) and unit cell parameters of a = 10.8736(3), b = 10.9560(4), c = 45.820(2) Å, β = 90.23(1)°, Z = 4. The TAMEN molecule acts as a hexadentate ligand incorporating a 1,2‐diaminoethane bridge in the staggered conformational gauche isomer. The nickel(II) ion is octahedrally coordinated with metal‐ligand distances ranging from 2.023(2) to 2.145(3) Å. Electronic and vibrational spectroscopy data agree well with the crystal structure.
