inary intermetallic compound Mo8Ga41 is considered as a non-typical superconductor with Tc = 9.7 K. Indeed, the normalized jump of the specific heat at Tc is cp/Tc = 2.83 [1]. This value indicates a much stronger electron-phonon coupling in the superconducting state of Mo8Ga41 than that in the weak-coupling BCS limit, where 1.43 is expected. Mo8Ga41 crystallizes in the V8Ga41 type of crystal structure with a complex network of gallium atoms occupying 9 crystallographic positions where Ga1 position in the center of a GaGa12 cuboctahedron with crystallographic position (0;0;0.5) has no contacts with Mo atoms in its first coordination sphere. Here we report NQR and preliminary NMR spectroscopy study of Mo8Ga41 based on ab-initio calculations of electric field gradient (EFG).
