| Abstract: | Two tri-n-butylphosphine-participated (PBu

3

)] 1 were synthesized and characterized by X-crystallography and1H NMR, FAB-MS and cyclic valtammogram measurements. The nickel (II) center in 1 has a square-planar geometry. For 3, the ruthenium
(III) atom is in a distorted octahedral environment and the two nickel (II) atoms exhibit squareplanar and rare triangle-planar
geometries, respectively. The Ni (1) -Ru-Ni(2) arrangement is severely asymmetric with the distances 0.254 and0.394 nm, respectively,
for Ni(1)-Ru and Ni(2)-Ru. The structural regularities of relevant complexes are summarized in relation to the structural
as well as spectra data. |
