چکیده
The mononuclear Ni(II) amide, [Ni(C(12)H(21)N(2)Si)(2)], has the Ni(II) atom N,N'-chelated by the N-silylated anilinide ligands. The ligands are arranged cis to each other and obey the C(2)-symmetry operation. The two ends of the N-Si-N chelating unit exhibit different affinities for the metal atom: the Ni-N(anilinide) bond length is 1.913 (3) Å and Ni-N(amine) is 2.187 (3) Å. The four-coordinate Ni(II) ion demonstrates a distorted tetra-hedral geometry.

The title compound, [Cu(2)(C(12)H(21)N(2)Si)(2)], is a binuclear Cu(I) complex. The dimeric mol-ecule has an inversion center located at the mid-point of the Cu-Cu bond [Cu-Cu = 2.7209 (7) Å]. The bidentate ligand behaves in an N:N'-bridging mode, coordinating the metal atoms. The N-Cu-N unit is close to being linear [176.60 (8)°]. The two N atoms exhibit different affinities for the metal atom...

The crystal structure of bis-(2-formyl-phenolato-κ(2)O,O')nickel(II), [Ni(C(7)H(5)O(2))(2)], a square-planar centrosymmetric complex, has been reported previously [Li & Chen (2006). Acta Cryst. E62, m1038-m1039]. However, a number of warning signs allows the assumption that the carbonyl group in the salicylaldehydate ligand of the claimed complex is incorrect. The crystal structure was therefor...
