  We describe the formation of fermionic NaLi Feshbach molecules from an
ultracold mixture of bosonic 23Na and fermionic 6Li. Precise magnetic field
sweeps across a narrow Feshbach resonance at 745 G result in a molecule
conversion fraction of 5% for our experimental densities and temperatures,
corresponding to a molecule number of 5*10^4. The observed molecular decay
ifetime is 1.3 ms after removing free Li and Na atoms from the trap.
