| (diazadien)metall(0)-Komplexe, IV [1] Nickel(0)-bis(chelate) mit aromatischen N-Substituenten Bis(diazadiene)metal(0) Complexes, IV [1] Nickel(0)-bis(chelates) with Aromatic N-Substituents R1R2 With N-aromatic substituted diazadienes (DAD) R 3 -N=C—C = N-R 4 (R 1 , R 2 = H, CH3 and R 3 = R 4 = aryl) nickel(O) forms complexes of composition (DAD)2Ni which are prepared preferably by reduction of Ni(II) salts in the presence of DAD. The groups R 1 , R 2 and/or the o-substituents of the aryl system determine the conformation of the DAD and its sterical ligand properties. An X-ray structure analysis of (DAD)2Ni 17 (DAD = glyoxal-bis(2,6-dimethyl-phenylimine)) shows a dihedral angle of 44° between the two chelate planes. With twisted N-aryl substituents nickel seems to prefer planar coordination (formal low spin Ni(II)) of two DADs over tetrahedrally coordinated formal nickel(O) state. | | | |
