| Summary: | 1T’-MoTe<sub>2</sub> has gained considerable attention owing to its topological character. This material undergoes spatial inversion symmetry at 300 K. A structural transition to the T<sub>d</sub> phase, which is represented by a kink in the resistivity, was observed below 250 K without inversion symmetry along the <i>c</i>-axis, while superconductivity was observed at 0.1 K. Substitution of Se into this material suppressed the appearance of the kink structure and increased the superconducting transition temperature to 2 K, which is consistent with previously reported results on polycrystalline samples. However, a specific heat jump was observed in the obtained single crystals, which did not exhibit kink structures in their resistivity. The results suggest that the T<sub>d</sub> structure was not suppressed entirely after Se substitution and that superconductivity was achieved without inversion symmetry.
