Conclusions<br />
Superconductivity <strong>in</strong> <strong>Mo</strong> 3<br />
<strong>Sb</strong> 7<br />
is analyzed us<strong>in</strong>g the comb<strong>in</strong>ed <strong>electron</strong>ic structure<br />
<strong>and</strong> <strong>phonon</strong> calculations.<br />
The <strong>electron</strong>-<strong>phonon</strong> <strong>coupl<strong>in</strong>g</strong> constant λ ph<br />
= 0.54.<br />
This value expla<strong>in</strong>s very well the experimental value of T c<br />
= 2.2 K.<br />
The possible <strong>in</strong>fluence of sp<strong>in</strong> fluctuations on the <strong>superconductivity</strong> <strong>in</strong> <strong>Mo</strong> 3<br />
<strong>Sb</strong> 7<br />
is found to be weak.<br />
