Element-Element-Bonds. VI. Crystalline 2-Chloro-1,3,2-benzoxathiastibole - a Multiply Linked Coordination PolymerYellow 2-chloro-1,3,2-benzoxathiastibole 4a first prepared by Anchisi and coworkers [3] from o-hydroxythiophenol and antimony trichloride, crystallizes in the monoclinic space group P21/n {a = 1109.9(3); b = 610.5(2); c = 1201.5(2) pm; β = 100.35(2)° at -120 ± 3°C; Z = 4}. An X-ray structure determination (R = 0.029) shows the molecules to form coordination polymeric layers via Sb…Cl, Sb…O and Sb…η2-arene interactions in the solid. Characteristic structural features are Sb—Cl…Sb—Cl helices (Sb—Cl…Sb 119°; Cl—Sb…Cl 95°) and centrosymmetric, four membered Sb2O2-rings (O—Sb…O 64°; Sb—O…Sb 116°). The ligands set up a strongly distorted octahedron around the antimony atom: Sb—S 242; Sb—Cl 243; Sb…Cl 328; Sb—O 201; Sb…O 287; Sb…C 338 and 341 pm; S—Sb—O 85°; S—Sb—Cl 94°; O—Sb—Cl 92°.
Notes:
Das nach ANCHISI und Mitarb. [3] aus o-Hydroxythiophenol und Antimon(III)-chlorid dargestellte, gelbe 2-Chlor-1,3,2-benzoxathiastibol 4a kristallisiert monoklin in der Raumgruppe P21/n {a = 1109,9(3); b = 610,5(2); c = 1201,5(2) pm; β = 100,35(2)° bei -120 ± 3°C; Z = 4}. Nach den Ergebnissen der Röntgenstrukturanalyse (R = 0,029) bauen die Moleküle im Kristall über Sb…Cl-, Sb… O- und Sb…η2-Aren-Wechselwirkungen koordinationspolymere Schichten auf. Charakteristische Strukturelemente sind Sb—Cl…Sb—Cl-Schrauben (Sb—Cl…Sb 119°; Cl—Sb…Cl 95°) und zentrosymmetrische, viergliedrige Sb2O2-Ringe (O—Sb…O 64°; Sb—O…Sb 116°). Die Liganden am Antimonatom bilden ein stark verzerrtes Oktaeder: Sb—S 242; Sb—Cl 243; Sb…Cl 328; Sb—O 201; Sb…O 287; Sb…C 338 und 341 pm; S—Sb—O 85°; S—Sb—Cl 94°; O—Sb—Cl 92°.
