Two isostructural new alkaline earth germanium nitrides, $Sr_6Ge_5N_2;and;Ba_6Ge_5N_2$, were obtained as single crystals from constituent elements in molten Na. They both crystallize in space group $P_{mmn}$ (No. 59) with a = 4.0007(8), b = 17.954(3), c = 9.089(2) $AA$, Z = 2, and a = 4.1620(2), b = 18.841(1), c = 9.6116(5) $AA$, Z = 2, for $Sr_6Ge_5N_2;and;Ba_6Ge_5N_2$, respectively. Their crystal structure contains features for both Zintl and nitride phases: zigzag anionic chain of $_{infty}Ge^{2-}$, and dumbbell-shaped bent anion of ${GeN_2}^{4-}$. Counter cations of Sr or Ba wrap these anionic units in a channel-like arrangement. Unlike in other germanium nitrides, bond lengths of both Ge-N arms of the ${GeN_2}^{4-}$, are same in $Sr_6Ge_5N_2;and;Ba_6Ge_5N_2$.
