N2 - The asymmetric unit of {[4,7-bis(2-aminoethyl)-1,4,7-triazacyclononan-1-yl]acetato}zinc(II) triaqua{μ-[4,7-bis(2-aminoethyl)-1,4,7-triazacyclononan-1-yl]acetato}lithium( I)zinc(II) chloride diperchlorate, [Zn(C12H26N5O2)][LiZn(C12 H26N5O2) (H2O)3]Cl(ClO4)2, obtained from the reaction between the lithium salt of 4,7-bis(2-aminoethyl)-1,4,7-triazacyclononane-1-acetate and Zn(ClO4)2, contains two ZnII complexes in which each ZnII ion is six-coordinated by five N-atom donors and one O-atom donor from the ligand. One carboxylate O-atom donor is not involved in coordination to a ZnII atom, but coordinates to an Li+ ion, the tetrahedral geometry of Li+ being completed by three water molecules. The two complexes are linked via a hydrogen bond between a primary amine N - H group and the carboxylate-O atom not involved in coordination to a metal.
