Abstract
We report the microwave synthesis and the doping effect of Mo3−x
Re

Al2C (0 ≤ x ≤ 0.3) superconductor. Re doping into Mo3Al2C results in a regular shrinkage of the lattice, marked by the linear decrease of lattice parameter a from 6.868(1) Å (for Mo3Al2C) to 6.846(2) Å (for Mo2.7Re0.3Al2C). Upon Re doping, T

Al2C first increases and then decreases, with the maximum T
c = 9.14 K at the optimal doping level of x = 0.09. Our report provides a convenient method to synthesize Mo3−x
