  We discuss the broadband X-ray spectrum of GRS 1734-292 obtained from
non-simultaneous XMM-Newton and NuSTAR observations, performed in 2009 and
2014, respectively. GRS1734-292 is a Seyfert 1 galaxy, located near the
Galactic plane at $z=0.0214$. The NuSTAR spectrum ($3-80$ keV) is dominated by
a primary power-law continuum with $\Gamma=1.65 \pm 0.05$ and a high-energy
cutoff $E_c=53^{+11}_{-8}$ keV, one of the lowest measured by NuSTAR in a
Seyfert galaxy. Comptonization models show a temperature of the coronal plasma
of $kT_e=11.9^{+1.2}_{-0.9}$ keV and an optical depth, assuming a slab
geometry, $\tau=2.98^{+0.16}_{-0.19}$ or a similar temperature and
$\tau=6.7^{+0.3}_{-0.4}$ assuming a spherical geometry. The 2009 XMM-Newton
spectrum is well described by a flatter intrinsic continuum
($\Gamma=1.47^{+0.07}_{-0.03}$) and one absorption line due to Fe\textsc{XXV}
K$\alpha$ produced by a warm absorber. Both data sets show a modest iron
K$\alpha$ emission line at $6.4$ keV and the associated Compton reflection, due
to reprocessing from neutral circumnuclear material.
