Arsenic selenide

Like the analogous sulfide, arsenic selenide exhibits photoinduced structural transformations when exposed to light. It is employed in optical imaging and storage and can be prepared by the CVD of a mixture of AsH.i and H2Se [135 a]. [Pg.380]

Arsenic selenide, As2Se3, is isomorphous with AS2S3. The reaction between As2Se3 and liquid ammonia gives a small yield of the unusual salt [NH4] [AsSe(NH2)2]. The latter loses NH3 to give NH2AsSe. [Pg.235]

The pentavalent arsenic selenide species has not been yet structurally characterized and it is produced in similar maimer to AS2S5. [Pg.235]

Mixed valent arsenic selenide compounds are known, and they are related to the arsenic sulfide species. For example, As4Se4 is isomorphous with realgar AS4S4 and As4Se3 is isomorphous with AS4S3. However, chemical reactivity is different due to the larger size of the selenium atom. ... [Pg.235]

Planar four-membered rings are again found in the dimeric species 64 and 65 . In the former, the geometry at tin(II) is pyramidal with As—Sn distances of 2.77 A and ring angles of 102.22 at arsenic and 77.78° at tin. Refinement of the arsenic selenide structure 65... [Pg.1018]
