The synthesis, crystal structures, and magnetic properties of the pentanary oxides PbM$$_2$$Ni$$_6$$Te$$_3$$O$$_{18}$$ (M = Mn and Cd) were investigated. These compounds crystallize in a hexagonal structure with space group $$P6_3/m$$, in which the Ni$$^{2+}$$ ions form a zigzag chain along the c axis. From the magnetic susceptibility and specific heat measurements, we found that the PbCd$$_2$$Ni$$_6$$Te$$_3$$O$$_{18}$$ behaves as a low-dimensional magnet due to the intrachain an tiferromagnetic interaction between Ni$$^{2+}$$ ions. Both compounds show a long-range antiferromagnetic ordering at 25.7 K (M = Cd) and 86.0 K (Mn). The magnetic structure of PbMn$$_2$$Ni$$_6$$Te$$_3$$O$$_{18}$$ determined by neutron diffraction measurements is a collinear antiferromagnetic arrangement of Mn$$^{2+}$$ ions in the Mn$$_2$$O$$_9$$ dimeric unit and Ni$$^{2+}$$ ions in the zigzag chain.
