Abstract

The reaction of the neutral dithiolene [Pd(Et2timdt)2] (Et2timdt = formally monoreduced diethylimidazolidine- 2,4,5-trithione) with an excess of Br2 yielded few crystals of [1Et·2Br]2+(Br2)2(Br2)3 as a by-product (1Et = 4,5,9,10-tet- rathiocino-[1,2-b:5,6-bA]-1,3,6,8-tetraethyl-diimidazolyl- 2,7-dithione); X-ray diffraction analysis showed that this compound represents the first example of a polybromide 2D- network templated by [1Et·2Br]+2 dications, and featuring all the Br–Br distances shorter than those found in solid state bromine.
