      abstract     = {SnGe$_4$N$_4$O$_4$ was synthesized at high pressure (16 and
                      20 GPa) and high temperature (1200 and 1500°C) in a
                      large-volume press. Powder X-ray diffraction experiments
                      using synchrotron radiation indicate that the derived
                      samples are mixtures of known and unknown phases. However,
                      the powder X-ray diffraction patterns are not sufficient for
                      structural characterization. Transmission electron
                      microscopy studies reveal crystals of several hundreds of
                      nanometres in size with different chemical composition.
                      Among them, crystals of a previously unknown phase with
                      stoichiometry SnGe$_4$N$_4$O$_4$ were detected and
                      investigated using automated diffraction tomography (ADT), a
                      three-dimensional electron diffraction method. Via ADT, the
                      crystal structure could be determined from single
                      nanocrystals in space group P63mc, exhibiting a
                      nolanite-type structure. This was confirmed by density
                      functional theory calculations and atomic resolution
                      scanning transmission electron microscopy images. In one of
                      the syntheses runs a rhombohedral 6R polytype of
                      SnGe$_4$N$_4$O$_4$ could be found together with the
                      nolanite-type SnGe$_4$N$_4$O$_4$. The structure of this
                      polymorph was solved as well using ADT.},
