[μ-N,N′-Bis(2-amino­eth­yl)ethane-1,2-diamine-κ⁴N¹,N^1′:N²,N^2′]bis­{[N,N′-bis­(2-amino­eth­yl)ethane-1,2-diamine-κ⁴N,N′,N′′,N′′′]cadmium} tetra­kis­(perchlorate)

The centrosymmetric dinuclear cadmium title complex, [Cd₂(C₆H₁₈N₄)₃](ClO₄)₄, was obtained by the reaction of N,N′-bis­(2-amino­eth­yl)ethane-1,2-diamine (trien) with Cd(NO₃)₂·4H₂O and sodium perchlorate in methanol. The Cd^II cation is coordinated by four N atoms of a non-bridging trien ligand and by two N atoms of a bridging trien ligand in a slightly distorted octa­hedral coordination geometry. The bridging ligand shares another two N atoms with a neighboring symmetry-equivalent Cd^II cation. The structure displays C—H...O and N—H...O hydrogen bonding. The perchlorate anion is disordered over two sets of sites in a 0.854 (7): 0.146 (7) ratio.
