title: Two gallium antimony sulfides built on a novel heterometallic cluster.
abstract: Two gallium antimony sulfides, [Ni(en)(3)][Ga(2)Sb(2)S(7)] (1) and [(Me)(2)NH(2)](2)[Ga(2)Sb(2)S(7)] (2), have been prepared under mild solvothermal conditions. Both structures feature a two-dimensional network in which two GaS(4) tetrahedra and two SbS(3) trigonal pyramids are combined to form a heterometallic cluster of {Ga(2)Sb(2)S(9)} as a new secondary building unit. The thermal properties of 1 and 2 have been studied by thernogravimetric analysis, and the optical properties of 1 and 2 have been characterized by UV-vis spectra.
