The results of NMR spectra and theoretical calculations showed that the hydroxamic acids were in the keto-E and keto-Z conformations. The elemental analysis and thermal analysis indicated that M:L ratio of the complexes are 1:1 and the spectral analysis confirmed that hydroxamate groups are keto form in the Ni(II) and Zn(II) complexes of 2-phenylbenzimidazole-N-butanohydroxamic acid and enol form in the other complexes. © 2016 Elsevier B.V.Elsevier B.V.2017Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/14958https://doi.org/10.1016/j.molstruc.2016.07.0810022-2860enJournal of Molecular Structureinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/14958
