摘要：

The crystal structure of tetraethylammonium pentachloroindate(III), ((C2H5)4N)2InCl5, has been determined from three-dimensional X-ray data collected by counter methods. The structure has been refined by least-squares techniques to a conventional R factor of 9.5% for the 811 observed reflections. The salt crystallizes in the tetragonal space group P4/n with two formula units in a cell of dimensions a = 9.374 (10) Å and c = 14.137 (10) Å. The calculated density of 1.48 g/cm3 is close to the measured value of 1.45 g/cm3. The pentacoordinate indium atom in the anion is bonded to five chlorines and has crystallographic fourfold symmetry. The apical In-Cl bond length is 2.415 (12) Å and the four basal bond lengths are 2.450 (7) Å. This anion is the first undistorted example of this geometry in a nontransition element. © 1969, American Chemical Society. All rights reserved.
