✦ Synopsis

Tetraphenylarsonium azide was prepared from the reaction of tetraphenylarsonium chloride monohydrate and sodium azide in aqueous solution. [Ph 4 As] ‫ם‬ [N 3 ] ‫מ‬ crystallizes in the orthorhombic space group P nma with Z ‫ס‬ 4 and unit cell dimensions a ‫ס‬ 16.539(2), b ‫ס‬ 10.879(2), and c ‫ס‬ 12.671(2) A ˚. The preparation of the compound [Ph 4 As] ‫ם‬ [SCSN 3 ] ‫מ‬ was also attempted; however, it was found that at temperatures Ն0ЊC, this compound always decomposed into the tetraphenylarsonium thiocyanate, [Ph 4 As] ‫ם‬ [SCN]
