Abstract: In the title compound, [Ni₂(C₅₂H₅₀N₄O₂)(C₂H₆O₂)](ClO₄)₂·2H₂O, the two Ni atoms are bridged by two O atoms from the Robson macrocyclic ligand, forming a parallelogram, which has a twofold axis. The macrocyclic plane is formed from an Ni₂O₂ center and four N atoms from the ligand. Above the macrocyclic plane an ethylene glycol molecule bridges the two Ni atoms, and the coordination geometry around each Ni atom is square pyramidal.
