Abstract
Abstract
[(C2H5)4N]2CuCl4 crystallizes in the tetragonal system (P42/nmc, a = 8.98(3) Å; c = 15.08(3) Å; Z = 2; R = 0.057, 442 hkl observed, 53 variables). The two (C2H5)4N+ and CuCl4
2− ions are disordered about intersecting mirror planes. CuCl4
2− ion has distorted tetrahedral symmetry with elongation along the tetragonal axis. In moist atmosphere, the compound is transformed, by hydration at solid state, into the hemihydrate: [(C2H5)4N]2CuCl4 · 0.5 H2O with tetragonal symmetry. The new 4 axis of the hydrated crystal is perpendicular to the 4 axis of the anhydrous crystal.
