The X-ray crystal structures of (4-methyl-4,7-diazadecane-1,10-diamine-N,N′,N″,N‴) (perchlorato-O)-copper(II) perchlorate, [Cu(C9H24N4)(ClO4)]ClO4, and (4-methyl-4,7-diazadecane-1,10-diamine-N, N′,N″,N‴)-nickel(II) diperchlorate, [Ni(C9H24N4)](ClO4)2, are isomorphous with minor dissimilarities. The copper(II) complex is six-coordinate in a distorted octahedral geometry, with the four N atoms of the tetradentate ligand equatorial and the two O atoms of the perchlorate groups axial. The nickel(II) complex is four-coordinate in a square-planar geometry. In both complexes, the conformations of the three consecutive six-, five- and six-membered rings are chair, gauche and chair, respectively. In both crystals, hydrogen bonds involving the amino groups and perchlorate O atoms help stabilize the crystal structure.
