The radio, infrared and optical counterparts of the hard X-ray source GRS 1734-292 (lII=358.9 deg, bII=+1.4 deg) are reported. The optical spectrum exhibits broad (>1000 km s-1) H alpha emission at a redshift of 0.0214 +/- 0.0005. The radio counterpart is a double-sided synchrotron jet of 5 arcsec, which at a distance of 87 Mpc corresponds to a size of 2 kpc. The multiwavelength observations of GRS 1734-292 indicate that this X-ray source is a Seyfert 1 galaxy behind 6 +/- 1 magnitudes of visual absorption.
