Abstract

A series of di (para-halophenyl) diselenides,(p-XC6H4) 2Se2 (X= F, Cl) have been reacted with three equivalents of SO2Cl2 or Br2, leading to the formation of selenium (IV) RSeX3 compounds. The structures of (p-FC6H4) SeX3 (X= Cl, Br) have been determined, and both exhibit a dimeric RSeX2 (μ-X) 2RSeX2 structure consisting of two “saw-horse”(p-FC6H4) SeX3 units linked by two halide bridges, with an overall square pyramidal geometry at ...
