Article abstract of DOI:10.1039/DT9830002263

The cationic nickel(I) complexes >ClO4 (1) and (PPh3)>ClO4 (2) have been synthesized by reaction of the nickel(0) derivative with ClO4 and the appropriate tripod-like ligand.The crystal structures of these two complexes have been determined from counter X-ray diffraction data.Crystal data: (1), space group Cc, a=16.599(9), b=12.810(7), c=18.650(9) Angstroem, β=90.3(1) deg, and Z=4; (2), space group P21/a, a=24.051(10), b=13.267(7), c=17.048(9) Angstroem, β=92.7(1), and Z=4.Both structures were solved by the heavy-atom method and refined by full-matrix least-squares techniques to R of 0.060.Compound (1) exhibits the uncommon trigonal-pyramidal geometry, the nickel atom being surrounded by the four phosphorus atoms of the ligand.In compound (2) the nickel atom is five-co-ordinated by the four donor atoms of the arsine ligand and by the phosphorus atom of the triphenylphosphine in a distorted trigonal-bipyramidal geometry.
