Nitride perovskites ABN3 are extremely rare with only two known instances of bulk-phase materials, ThTaN3 and LaReN3. Here, we present a powder neutron diffraction study the recently-reported nitride perovskite A full structural model LaReN3 at 300 K ( , a=5.58523(5), b=5.59297(5), c=7.90419(6) Å, α=89.9170(8), β=90.1729(7), γ=90.1709(7)°) has been refined simultaneously against previously-coll...

While halide and oxide perovskites are numerous many display outstanding properties, ABN3 perovskite nitrides extremely rare due to synthetic challenges arising from the low chemical potential of nitrogen a tendency form low-coordination nitridometallate anions. We report preparation nitride LaReN3 through azide-mediated oxidation at high pressure. High-resolution synchrotron diffraction shows ...

THE TITLE COMPOUND (SYSTEMATIC NAME 2-mercaptoethan-aminium chloride), C(2)H(8)NS(+)·Cl(-), the hydro-chloride salt of cysteamine, in contrast to the previously reported triclinic polymorph [Kim et al. (2002 ▶). Polyhedron, 21, 225-228], crystallized in the monoclinic crystal system. In the crystal, the cysteaminium cations are linked to the chloride anions via one S-H⋯Cl and three N-H⋯Cl hydro...
