The material described by SnBr4 is Silicon tetrafluoride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four tin(iv) bromide molecules. Sn(1) is bonded in a tetrahedral geometry to one Br(1), one Br(2), one Br(3), and one Br(4) atom. There are four inequivalent Br sites. In the first Br site, Br(1) is bonded in a single-bond geometry to one Sn(1) atom. In the second Br site, Br(2) is bonded in a single-bond geometry to one Sn(1) atom. In the third Br site, Br(3) is bonded in a single-bond geometry to one Sn(1) atom. In the fourth Br site, Br(4) is bonded in a single-bond geometry to one Sn(1) atom. is represented by the CIF card [CIF]
