N,N'-Diphenylformamidinato gold(I) (1) is obtained from Na(PhNCHNPh) and AuI in liquid ammonia.It can be recrystallized from toluene/n-heptane to form colorless monoclinic crystals, the space group C 2/c, with the lattice constants a = 1781.7(7), b = 1159.0(5), c = 2518.7(8) pm, β = 99.06(3) deg. 1 is tetrameric in solution and in the solid state.In the tetrameric complex with the symmetry C2 the four Au atoms form a planar rhombus with Au-Au distances between 295.7 and 322.7 pm.The amidinato ligands are arranged alternatively above and below the Au4-rhombus and function as bridging ligands for neighbouring Au atoms, which thereby reach a linear coordination with distances Au-N between 200.0 and 202.4 pm. - Keywords: N,N'-Diphenylformamidinato Gold(I), Synthesis, Crystal Structure
