      abstract     = {Three new sodium thorium arsenates, Na5Th4(AsO4)7 (1 ),
                      Na5Th(AsO4)3 (2 ), and Na4Th(As2O7)2 (3 ) were synthesized
                      via a high temperature route and their structures and
                      optical properties were studied. Compound 1 adopts a
                      three‐dimensional structure that consists of tetrameric
                      fundamental building blocks (FBBs) [Th4(AsO4)7]5–, which
                      are constructed by ThO8 and ThO9 polyhedra. The structures
                      of 2 and 3 are based on open frameworks with channels
                      running along the a or c axes, respectively, which are
                      occupied by Na cations. Structural relations between the
                      structures of 2 and 3 have been discussed regarding their
                      composition. In contrast to the other two compounds, the
                      arsenate anions in the structure of 2 play role of bridging
                      ligands and do not connect more than two Th atoms. Owing to
                      this, the underlying net of this compound contains only Th
                      nodes has a lon topology. The Raman spectra of 1 and 2
                      contain similar peaks due to As–O vibrations of AsO4
                      groups, while the Raman spectrum of 3 differs significantly
                      owing to the presence of As–O–As bridging group in
                      As2O74– anions.},
