Calculations of electronic structure and bonding via the SCMEH‐MO method with limited Cu 3 d , 4 s , and 4 p configuration interaction, have been carried out on the tetragonally coordinated (D 2h symmetry) CuCl 6 (NH 4 ) 4 structural cluster unit in crystalline (NH 4 ) 2 CuCl 4 . The results are compared with those of other calculations. The calculated electronic spectrum, electric field gradient ( EFG ), and magnetic data are compared with experiment. © 1992 John Wiley & Sons, Inc.
