In the title salt, [CrCl(2)(C(5)H(14)N(2))(2)]ClO(4), the Cr atom is in a trans-CrCl(2)N(4) octa-hedral environment comprising the four N atoms of two chelating 2,2-dimethyl-propane-1,3-diamine ligands and two Cl atoms. The two six-membered CrC(3)N(2) rings in the cation adopt anti chair-chair conformations with respect to each other. The perchlorate anion is disordered over two positions in respect of the Cl and an O atom in a 6:4 ratio. N-H⋯O hydrogen bonds link the cations and anions into a layer structure.
