Tetraethylammonium tetrachlorocuprate(II), [N(C2H5)4]2[CuCl4]

Abstract

The structure has been determined by single-crystal X-ray diffraction at 120 K. There are two independent copper sites, one at 4 and the other very close to the fourfold axis with positional disorder. The structures of the [CuCl 4 ] 2- ions have a D 2d type distortion from tetrahedral symmetry with the larger Cl-Cu-Cl bond angles 122.3 (1)-128.1 (5) o
