Is nickel dibromide bent in a nitrogen matrix? A combined simultaneous Fourier-transform infrared and X-ray absorption fine structure matrix isolation study
Abstract
Combined Fourier-transform (FT) IR and X-ray absorption fine structure (XAFS) studies of NiBr2 isolated in a nitrogen matrix have shown that it is non-linear (125° FTIR, 145° XAFS), with the shortest Ni–Nmatrix interaction at 2.61 Å, compared to a linear geometry in a methane matrix.
