“…This paper describes the results of the isolation of the 3d transition metal dibromides of Fe, Co, Ni, and Zn in matrices of noble gases (Ne, Ar, Kr, Xe) as well as CH 4 and N 2 , with O 2 also being employed in the NiBr 2 studies. While the difluorides and dichlorides of the 3d transition metals have been widely studied, the available data in the matrix isolation literature for the dibromides are much more scarce and are limited to NiBr 2 in Ar, ZnBr 2 in Kr, ,,, and CrBr 2 in Ar . We have published two preliminary pieces of work on NiBr 2 in N 2 matrices. , The paucity of spectroscopic data for the transition metal dibromides has also been highlighted .…”

The interactions of FeBr, CoBr, NiBr, and ZnBr with Ne, Ar, Kr, Xe, CH, and N matrices have been investigated using IR, electronic absorption, and X-ray absorption spectroscopies as well as DFT calculations. ZnBr is linear in all of the matrices. NiBr is linear in all but N matrices, where it is severely bent. For FeBr and CoBr there is a more gradual change, with evidence of nonlinearity in Xe and CH matrices as well as N. In the N matrices, the presence of ν modes blue-shifted from the "free" N values indicates the presence of physisorbed species, and the magnitude of the blue shift correlates with the shift in the ν mode of the metal dibromide. In the case of NiCl and NiBr, chemisorbed species are formed after photolysis, but only if deposition takes place below 10 K. There was no evidence for chemisorbed species for NiF and FeBr, and in the case of CoBr the evidence was not strong.
