The title structure, [CuCl(C 4 H 13 N 3 )]Cl, consists of alternating [CuCl(dien)] + (dien is diethylenetriamine) and Cl − ions arranged in quasi‐one‐dimensional stacks along the crystallographic a axis and forming tetragonally elongated octahedral coordination shells around each Cu atom [equatorial Cu—Cl = 2.2552 (8) Å, and axial Cu—Cl = 2.831 (1) and 3.341 (1) Å]. Crystallographic mirror planes bisect each stack vertically through the Cu, Cl and central N atoms, and horizontally through the [CuCl(dien)] + cation. The horizontal mirrors lead to each atom in the puckered [CuCl(dien)] + cations being disordered over two crystallographically equivalent sites. Comparison of the title structure with its Br and I analogues shows a growing influence of hydrogen bonding relative to coordination bonds on traversing the series I < Br < Cl.
