  摘要：

  The tetrameric arsenic-oxygen heterocycle tetramethyl-cyclo-tetraarsaoxane, cyclo-(CH3AsO)4, is obtained as a crystalline single phase from the aerobic oxidation of homocyclic pentamethyl-cyclo-pentaarsine, cyclo-(CH3As)5, via a metal-carbonyl template reaction using Mn2(CO)10. A chair-boat ring conformation for this cyclooctane analogue has been determined crystallographically: C4H12As4O4, monoclinic, P2(1)/n, a = 9.229 (3) angstrom, b = 8.848 (3) angstrom, c = 14.760 (5) angstrom, beta 95.04 (3)-degrees, V = 1200.6 (7) angstrom3, Z = 4, R(F) = 5.28%. The arsaoxane ring readily forms complexes in which two of the four arsenic atoms function as two-electron donors. With methylcymantrene, Cp'Mn(CO)3, [Cp'Mn(CO)2]2[cyclo-(CH3AsO)4] is formed. The eight-membered ring is found crystallographically in a chair conformation, likely for steric reasons: C20H26As4Mn2O8, monoclinic, P2(1)/n, a = 10.842 (2) angstrom, b = 9.418 (2) angstrom, c = 14.146 (3) angstrom, beta = 107.49 (2)-degrees, V = 1377.7 (5) angstrom3, Z = 4, R(F) = 3.59%.
