Properties of the tetraethynylborate anion as a ligand in reactions with tetraamine complexes of nickel(II)
New tetra- and hexaamine complex compounds of nickel(II) with mono-, bi-, and tetradentate linear or cyclic amines of the aliphatic series containing both outer-sphere tetraethynylborate anions and (B(C identical with CH)/sub 4/)/sup -/ anions which are coordinated to the metal ion have been synthesized. The possibility of the coordination of ligands having strong acceptor properties in the axial positions of square-planar complexes of nickel(II) has been demonstrated. The dative transfer of electron density from a nickel(II) 3d/sub xz, 3d/sub yz/, or 3d/sub z/sup 2// orbital occupied by an electron pair to vacant acceptor orbitals of the axial ligands, for example, the antibonding ..pi.. orbitals of the C identical with C bonds of the tetraethynylborate anion is allowed in this case.
