μ-NN′-Bis(2-amino­eth­yl)ethane-12-diamine-κ4N1N1′:N2N2′bis­{NN′-bis­(2-amino­eth­yl)ethane-12-diamine-κ4NN′N′′N′′′cadmium} tetra­kis­(perchlorate)

摘要

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.
