Sumario:The title quaternary compound, dibarium tetra­anti­mony germanium deca­sulfide, Ba(2)Sb(4)GeS(10), crystallizes in a novel three-dimensional (∞) (3)[Sb(4)GeS(10)](4−) network structure, which is composed of triangular pyramidal SbS(3) (site symmetry m..), distorted SbS(5) (m..) polyhedra and regular GeS(4) (-4..) tetra­hedra. The SbS(3) and SbS(5) units are connected with each other through corner- and edge-sharing, forming a Sb(4)S(10) layer in the ab plane. The GeS(4) tetra­hedra further bridge two neighbouring Sb(4)S(10) layers, forming a three-dimensional (∞) (3)[Sb(4)GeS(10)](4−) network. The Ba(2+) cation (..2) is located between two Sb(4)S(10) layers and is coordinated by ten S atoms with Ba—S bond lengths in the range 3.2505 (9)–3.4121 (2) Å.
