This work presents for the first time the high-spin information on the odd-odd neutron deficient nucleus ${}_{}{}^{92}{}_{}{}^{}\mathrm{Tc}$. We have used the reaction ${}_{}{}^{64}{}_{}{}^{}\mathrm{Zn}$${(}^{35}$Cl,4p3n${)}^{92}$Tc at a beam energy of 140 MeV to populate high-spin states in the N=49 nucleus ${}_{}{}^{92}{}_{}{}^{}\mathrm{Tc}$. Gamma-ray intensities and γ-γ coincidences were measured. Nineteen new transitions have been found and placed in a level scheme. The positive and negative parity bands have been extended tentatively up to a spin of ${17}^{+}$ and ${21}^{\mathrm{-}}$, respectively. The level scheme can be reasonably well understood within the (${\mathit{p}}_{1/2}$,${\mathit{g}}_{9/2}$) model space and breaking of the N=50 neutron core. We have observed two discrepancies in the earlier work on the low-lying states in ${}_{}{}^{92}{}_{}{}^{}\mathrm{Tc}$.
