Arsenic pentachloride is a metastable inorganic chemical compound of arsenic from the group of chlorides .

Extraction and presentation

Arsenic pentachloride can be obtained by photochemical chlorination of arsenic (III) chloride at −105 ° C.

{\ displaystyle \ mathrm {AsCl_ {3} + Cl_ {2} \ longrightarrow AsCl_ {5}}}

properties

Arsenic pentachloride is a metastable compound; its decomposition is catalyzed by hydrogen chloride . The noticeable instability of the connection is z. Partly attributed to the transition metal contraction, partly to the weakness of the AsCl bond. Above −50 ° C it breaks down again into arsenic (III) chloride and chlorine. The compound has a trigonal bipyramidal geometry and crystallizes in the orthorhombic space group Pmmn (space group no. 59) . Template: room group / 59
