Description	Brown crystals of [NMe4]4[(Se4Br10)2(Se2Br2)2] (1) were obtained from the reaction of selenium and bromine in acetonitrile in the presence of tetramethylammonium bromide. The crystal structure of 1 was determined by X-ray diffraction and refined to R = 0.0297 for 8401 reflections. The crystals are monoclinic, space group P21/c with Z = 4 and a = 12.646(3) A, b = 16.499(3) A, c = 16.844(3) A, = 101.70(3)deg (123 K). In the solid-state structure, the anion of 1 is built up of two [Se4Br10]2- ions. Each shows a triangular arrangement of three planar SeBr4 units sharing a common edge through two 3-bridging bromine atoms, and one SeBr2 molecule, which is linked to the SeII atoms of two SeBr4 units; between the Se4Br102- ions a dimerized Se2Br2 molecule (Se4Br4) is situated and one SeI atom of each Se2Br2 molecule has two weak contacts [3.3514(14) A and 3.3952(11) A] to two bromine atoms of one SeBr4 unit. Four SeI atoms of a dimerized Se2Br2 molecule are in a almost regular planar tetraangular arrangement.
