We report the production of $^87$RbCs Feshbach molecules in a crossed-beam
dipole trap. A mixture of $^87$Rb and $^133$Cs is cooled close to quantum
degeneracy before an interspecies Feshbach resonance at 197\,G is used to
associate up to $\sim5000$ molecules with a temperature of $\sim300$\,nK. The
molecules are confined in the dipole trap with a lifetime of 0.21(1)\,s, long
enough for future experiments exploring optical transfer to the absolute ground
state. We have measured the magnetic moment of the Feshbach molecules in a
magnetic bias field range between 181 and 185\,G to demonstrate the ability to
control the character of the molecular state. In addition we have performed
Feshbach spectroscopy in a field range from 0 to 1200\,G and located three
previously unobserved resonances at high magnetic fields.
