Abstract: The crystal structure of the low-temperature phase of diethylammonium tetrachloridocuprate(II), (C4H12N)2[CuCl4], has been determined by Simonsen & Harlow [(1977). Am. Crystallogr. Assoc. Ser. 2 Vol. 5, No. 1, Abstract HN5], but no atomic coordinates are available. We therefore redetermined the structure at 100 K. It comprises three crystallographically independent formula units linked by hydrogen bonds into a two-dimensional network. One tetrachloridocuprate(II) anion is virtually square-planar while the two others are tetrahedrally distorted.
