Abstract
The salt (NBu4)2[Zn(dsit)2] 6 has been converted into the polymer (C3S3Se2)n 7 which is a source of the reactive 1,2-diselone 8, trapping of which with dimethyl acetylenedicarboxylate affords the 1,4-diselenine derivative 9, which is subsequently transformed into the 1,4-diselenine-2,3-dithiolate species 11, characterised by the X-ray crystal structure of a nickel complex 12.Keywords
