The structure of the quasar 3C 345 and of the Seyfert galaxy NGC 1275 has been studied at lambda = 18 cm with a global VLBI network. Within 3C 345 are a nucleus and a compact feature, both measuring roughly-equal 0''.0003, accompanied by a thin jet that weakens and bends with distance from the nucleus. In NGC 1275 the compact central feature observed at shorter lambda is absent at 18 cm, probably because of synchrotron self-absorption as well as absorption in ionized gas surrounding the nucleus.
