The novel dinuclear Ni 2+ complex [Ni 2 ( μ ‐Cl)( μ ‐OAc) (EGTB)]·Cl·ClO 4 ·2CH 3 OH, where EGTB is N, N, N′, N′‐tetrakis (2‐benzimidazolyl methyl‐1, 4‐di‐ethylene amino)glycol ether, crystallizes in the orthorhombic space group Pnma with a = 15.272(2), b = 14.768(2), c = 22.486(3) Å, V = 5071.4(12) Å 3 , Z = 4, D calc = 1.414 g cm −3 , and is bridged by triply bridging agents of a chloride ion, an acetate and an intra‐ligand (‐OCH 2 CH 2 O‐) group. The nickel coordination geometry is that of a slightly distorted octahedron with a NiN 3 O 2 Cl arrangement of the ligand donor atoms. The Ni–Cl distance is 2.361(2) Å, and two Ni–O distances are 1.996(5) and 2.279(6) Å. The three Ni–N distances are 2.033(7), 2.060(6), and 2.166(6) Å with the Ni–N bond trans to an ether oxygen the shortest, the Ni–N bond trans to an acetate oxygen the middle and the Ni–N bond trans to Cl the longest.
