tBu6As8 - a Compound of Known Composition and New StructureThe compound 2,2′,3,3′,4,4′-hexatertiarybutyl-1,1′-bicyclotetraarsane (1) can be obtained in good yields through the reaction of (tBuAs)4 with [Co2(CO)8]. 1 is the structural isomer of 2,3,4,6,7,8-hexatertiarybutylbicyclo-[3.3.0]octaarsane (2) described in 1981 by Baudler et al. . 1 was characterized by 1H-NMR spectroscopy, mass spectroscopy and crystal structure analysis. Isomerisation into 2 can be observed, by tempering a solution of 1 in toluene for ten hours at 90°C.
