Ni 4 O 4 cubanes [(μ 3 -L 1 O)NiCl(MeOH)] 4 (1) and [(μ 3 -L 2 O)NiCl(H 2 O)] 4 (2) (L 1 OH = 1-H-2-benzimidazolylmethanol, L 2 OH = 1-methyl-2-benzimidazolylmethanol) self-assemble from commercially available 1-H- and 1-methyl-2-benzimidazolylmethanol and NiCl 2 ·6H 2 O in high yields under mild conditions. Both complexes were characterised spectroscopically and by X-ray crystallography. The cubanes oxidise water electrocatalytically to dioxygen at neutral pH in aqueous potassium phosphate buffer solutions.
