N2 - A new phase has been prepared by methanolothermal reaction of Cs2CO3, BiCl3 and Li3AsSe3 at 130 °C for 36 hours. Cs4BiAs3Se7 (I) reveals the first Bi-selenoarsenate polyanionic chain 1∞[Bi(As2Se4)(AsSe3)] 4-, consisting of Bi3+ ions in a distorted octahedral environment of [AsSe3]3- and trans-[As2Se4]4- units. The latter anion consists of a central "As24+" dumb-bell whereby two Se atoms are attached to each of the As atoms. Structural Data: Space Group P21/n, a = 13.404(4) Å, b = 23.745(8) Å, c = 13.880(4) Å, β= 99.324(6)°, Z = 8.
