We present the results of a 21 cm line study of the environment of two Seyfert galaxies: NGC 6764 and Mrk 1126. Both galaxies are embedded in large and slightly distorted gaseous disks that extend 2-4 times farther than their optical diameters. The asymmetry of the H I distribution and profile is indicative of a weak perturbation, although one that is not strong enough to disturb either the gas or the stars in the inner parts of the galaxies. Whereas Mrk 1126 does have a nearby companion, MCG -02-58-017, the gravitational interaction between the two galaxies is quite weak, and it is unlikely that MCG -02-58-017 is responsible for driving the nuclear activity in Mrk 1126. NGC 6764 has no companions within a radius of 160 kpc. We conclude that the nuclear activity in NGC 6764 and Mrk 1126 is unrelated to the galaxies' immediate environment.
