Isolierte I102--ringe, ein neues strukturelement in der polyiodid-chemie
The novel compound bis(1,4,7,10-tetraoxacyclododecane)cadmium(II) decaiodide, [Cd(C(8)H(16)O(4))(2)]I(10), contains the [Cd(12-crown-4)(2)](2+) complex cation, triiodide ions and iodine molecules. Two triiodide ions and two iodine molecules form isolated twisted I(10)(2-) rings. The geometry of the complex cation is as expected, e.g. d(Cd-O) = 2.366 (4) and 2.394 (4) A.
