Mj. Ashcroft et al., NICKEL L-EDGE X-RAY-ABSORPTION STUDY OF NICKEL PHOSPHINE HALIDE-COMPLEXES, Physica. B, Condensed matter, 209(1-4), 1995, pp. 725-726
Nickel L(III,II) absorption spectra of [NiX(2)P(2)] or [NiX(2)(P-P)] (
where X = Cl, Br and P = PEt(3), PPh(3) and P-P = dppe) are shown to b
e very sensitive to the local Ni environment and able to differentiate
between tetrahedral, cis-square planar and trans-square planar geomet
ries.
