Powder-EPR studies at T = 295 K and T = 12 K on the unstable gold(II) complex [(n- C4H9)4N]2[AuII(mnt)2] diamagnetically diluted by the corresponding NiIIcomplex are reported. Due to (i) the small anisotropy of the g and the 197Au hyperfine tensor AAu, and (ii) the large 197Au quadrupole interaction the powder spectra possess a very complex pattern. Using different EPR frequencies - S band (2.4 GHz), X band (9.5 GHz), Q band (35 GHz) and W band (94 GHz) - the spectra could be analyzed successfully. All spectra were simulated with a computer program which diagonalizes the spin-Hamiltonian matrix exactly.
